Bits of Entrance Lock have been coned off for ages, mostly the area with the lockkeepers' house on it. My friends Sarah and Vik mentioned at the weekend that it had recently been un-coned, so I wandered that way to cross the outermost lockgates for the first time this year. I don't know whether it's just my mood today or the weather, but it seemed a day for pushing a couple of photos in a more experimental direction in the post-processing...
I hadn't really planned to go out for a wander yesterday; I just got the urge and thought "why not?" (Well, the weather forecast was one possible reason, but I managed to avoid the rain, luckily.)
I wanted to finish off the A369—as it turns out I may still have a small section to go, but I've now walked the bulk of it out to my one-mile radius—and also a few random tracks in Leigh Woods. I'm still not really sure that I'm going to walk them all, especially after discovering today that "the map is not the territory" applies even more in the woods, where one of the marked tracks on the map wasn't really that recognisable as a track in real life... I'm glad I'd programmed the route into the GPS in advance!
Anyway. A pleasant enough walk, oddly bookended, photographically at least, by unusual vehicles. Leigh Woods was fairly busy, especially the section I'd chosen, which was positively dripping with teenage schoolkids with rah accents muttering opprobrium about the Duke of Edinburgh. I'm presuming the harsh remarks were more about taking part in his award scheme than the late Consort himself, but I didn't eavesdrop enough to be certain...
I'm not sure what's being delivered to the lock-keepers' house, but it looks like they'll probably all be a lot happier afterwards.
There were only a few streets left to wander in the more residential bit of Bedminster, so I thought I should target those today. The streets themselves weren't that notable, though Balfour Road has a contrasting mix of old and new housing. I tried to snap a few more interesting things along the way there and back, snapping all three of the familiar bond warehouses, nipping onto North Street to find some new street art, and finding a few pumpkins for good measure. It is hallowe'en, after all...
You can see the disturbance in the water on the river side as the sluices drain water from the lock to equalise the levels.
Bower Ashton is an interesting little area just south of the river from me—in fact, the Rownham Ferry used to take people over from Hotwells to Bower Ashton, operating from at least the twelfth century to around the 1930s.
It's a strangely contradictory little area, with a cluster of old and new houses sandwiched in between the busy A-roads and significantly more industrial area of Ashton and the bucolic country estate of Ashton court roughly east to west, and also between Somerset and Bristol, north to south.
I've been around here before, mostly poking around Bower Ashton's arguably most well-known bit, the Arts faculty campus of the University of the West of England, but I'd missed at least Parklands Road and Blackmoors Lane, so I initially planned just to nip across briefly and wander down each in turn. On a whim, though, I texted my friends Sarah and Vik in case they were out and about, and ended up diverting to the Tobacco Factory Sunday market first, to grab a quick flat white with them, extending my journey a fair bit.
To start with, though, I nipped to a much more local destination, to see something that you can't actually see at all, the Gridiron...
(I also used this wander as a test of the cameras in my new phone. I finally upgraded after a few years, and the new one has extra, separate wide and telephoto lenses compared to the paltry single lens on my old phone. Gawd. I remember when speed-dial was the latest innovation in phones...)
You can't actually see the Gridiron in this photo, but I believe it's still there, under that amazing buildup of silt.
The Gridiron—one of the few photos of it can be seen on the Maritime Mud and Miasma page of About Bristol—was a cheaper alternative to putting your boat in a dry dock. It was a 200-foot long grid (there seems to be some debate over whether the grid itself is actually metal, or in fact timber; I'll have to try to find out), 38 feet wide, nestled here between the north and south entrance locks. A ship captain could sail his vessel over here at high tide, then as the tide gradually receded, the ship—up to 250 feet, as overhanging a bit was apparently okay—would settle onto the gridiron.
At that point an inspection and repair crew could make their way down to the gridiron by ladder and do whatever work they could manage before the tide rose up again.
You can still see some ladders in place, I can only presume they were there to get you down to the gridiron, but that is just a guess; information on it seems quite hard to find.

As you can see, it was pretty big, and clearly still in use in 1946...
One last snap before we move on. I'm using the wide lens on the iPhone here, and have managed to include a silhouette selfie...
On my last wander, to Bower Ashton, I was intending to knock Blackmoors Lane off my list "to-do" list, but got a bit diverted. I also took a little look into the history of the Gridiron, once a cheaper alternative to dry dock that was nestled just south of North Entrance Lock.
Today I had to go to send a parcel off somewhere, so I decided on going to the North Street Post Office via Blackmoors Lane. I didn't have much intention of anything else, but as luck would have it I walked out both at low tide and also as some lockkeepers seemed to be having a bit of a training session, and one of the more senior people was (a) happy to answer a few random questions on the Gridiron and (b) actually knew a lot about it, as Gridiron maintenance had been one of his jobs, more than twenty years ago...
If you look at the lock wall, about halfway between the lock gates and the inset ladder, you'll see a little square hole. I had no idea what it was for until today, and I had no idea I was going to find out...
There were various people on the other side, I got the impression it was some kind of training session, perhaps. Later I'll have a quick chat with the man in the high-vis jacket over there.
In the meantime, I do always enjoy seeing the giant gridded lock gates uncovered by a low tide.
This used to be a view of the Gridiron, the structure I mentioned on yesterday's wander.
I got curious and went back to ask one of the lockkeepers about it. As it turned out, he knew lots about it as he'd previously been responsible for cleaning it! More about that when I come back (including a historical photo of a boat on the Gridiron for some context) as some of the things he told me needed me to retrace my steps for some more photos.
First, though, we'll nip over to Bower Ashton and North Streeet for a quick bit of shopping and to knock Blackmoors Lane of my "to do" list.
If you recall, before I left this area on the outbound leg of the wander, I had a chat with one of the more senior lockkeepers. He told me that the gridiron was definitely still there, and, look—there at the far left-hand side. What's that poking out of the silt?
Yes, having compared it with old photos and the 1946 aerial view I posted on Sunday I'm sure that that's the end of the gridiron, all 200 feet of which is apparently still there beneath the silt.
The lockkeeper told me that the gridiron was in use as recently as 2000, and that it used to be his job to wash the silt build-up away, using a sluicing system we'll get to in a moment.
I didn't realise I'd buggered up the focus on this shot until I got home and saw it on the big screen. They can't all be winners...
I've always wondered what this wheel is for. It's part of the Gridiron's cleaning system. Water is drawn from North Entrance Lock through a sluice channel and could be diverted one way and another across the surface of the gridiron. I wasn't clear from my conversation with the lockkeeper whether this would open the sluice channel or was the control used to divert the water first to the left of this central point of the gridiron, then to the right, but it's definitely part of the cleaning mechanism.
He said he also used to have to go down the ladder and hose it all down after sluicing it out, and that he found the whole process quite fun!
This is about halfway along the Gridiron. You'd sluice water back and forth from this point to rinse the silt off the Gridiron as part of its regular maintenance. This was still being done until around the year 2000, when it apparently became more trouble/cost than it was worth for the dwindling number of boats using it.
I mostly went out to hang out with my friends Sarah and Vik in Bedminster, but along the way I thought I'd take a closer look at something a little nearer home: the last crossing point of the Rownham Ferry.
That reminds me; I must re-read Iain M Banks's Use of Weapons again. In the novel he used the name Size Isn't Everything for one of the Culture's General System Vehicles, a spacecraft approximately 80km long... In the Culture, spacecraft are sentient and Culture ships choose their own names, often ironically.
He we have something of the opposite size of craft.
I was originally going to head over to the Ashton area to see if I'd missed any bits around the football stadium—and also to grab some lunch from the Tobacco Factory Market—but in the end I got a little distracted by having accidentally chosen exactly the right time to see the Plimsoll Bridge swing on one of the first busy days of Spring, where a lot of pleasure trips tend to head out down the Avon (and possibly the New Cut) from Hotwells.
In the end I mostly snapped that, and just a couple of photos from the Ashton area where I grabbed some lunch but didn't do any new exploring.
My first hint that there might be something interesting to look at was that the lock gates that I was planning on walking over were open rather than closed. Then I spotted the pleasure boat in the lock, just behind the descending steps from the footbridge there.
The Plimsoll Bridge is definitely not the oldest swinger in town. In fact, it may be the youngest swinger in town. I think the only other functioning swing bridges on the floating harbour (side-to-side rather than up-down like Redcliffe Bascule) are Junction Bridge (hidden in this picture, it's on the far side of the Cumberland Basin, carrying Merchants Road) and Prince Street Bridge, built in 1925 and 1879 respectively. The Plimsoll Bridge is mid-1960s.
You don't often see this view of the brutalist bridge abutment, because the bridge itself is normally blocking and overshadowing the view here. Excuse me while I take far too many photos of it to be healthy.
I've always particularly liked the spiral staircases and the control tower, which looks like it's escaped from a prison camp.
The brutalist bridge abutment is the old bit, of course, as it's mid-1960s. The boat that looks like John Cabot's 15th century caravel is the new bit. This replica was made in the 1990s, and replicated the original's 1497 trip to Newfoundland in 1997, arriving in June at Bonavista, to be greeted by Queen Elizabeth.
She's just had her annual inspection in the Albion dry dock, so I suppose this is one of her first gorge trips of the summer season.
You can see the man whose job it is to work the rather complicated-looking controls in the control tower has come out onto his balcony now the opening procedure is done.
Another day not dissimilar to my last wander: I'm feeling a bit tired and rather than just moping around the house I thought I'd find some tiny bit of somewhere that I'd not yet walked and get outdoors. This time I headed for the Tobacco Factory Market in Bedminster, as I often do, but went the long way around via Ashton Court Mansion as I knew there were some footpaths and a small section of road I'd not ticked off up there. Finishing all the Ashton Court footpaths will be quite a long job, but you've got to start somewhere...
I did feel rather better by the time I got home, and, pretty much astoundingly given the weather forecast, managed to avoid the rain completely.
Fairly typical Bristol scene here, as the traffic is held up for a bridge swing caused by a replica of a 15th century caravel.
I'd normally walk over those open lock gates she's just sailed through, but it's easy enough to walk down to the gates at the river end.
I've been pretty awful at reading so far this year, apparently averaging about one book per month. That's a far cry from 2019, say, where I got through 41 books in the year. Today's wander was prompted by my rubbish reading, as I needed to go hand back some books to the library, because I'd managed to renew them so many times that I hit the limit on renewals. Oops. Several of them were still unread.
So, off to the Central Library for me, tail between my legs. On the way there I did my best to recreate a historical photo of Dowry Square; while I was in the area I walked under the adjacent Norman arch and poked around behind the Cathedral, and I also had a little diversion to the city centre and came back along the south side of the river, hitting some trouble with the lock gates as I finally crossed the harbour back towards home.
While I was taking the last few photos I'd been hearing the two-tone alarm signal of a bridge swing, so I knew something would be going on at the lock when I got here. This time, though, I got more than I bargained for.
I was coming up to cross at these lock gates like normal when I saw that the lock keeper operating the hydraulics was having some difficulties. Sure enough, after a few attempts at closing the gates, it became apparent that they just weren't having any of it. They were getting this close to closing and then jamming.
...which was good in some ways; I've always been curious about the control panel for the lock gates, and as the lockkeeper went to have a closer look at the gates themsevles I took this snap and, in the next photo, a close-up.
There's something very pleasing about industrial switchgear to me. This is comparatively modern, put in the last time the lock gates were replaced/refurbished, from what I remember, but still has that pleasingly 1950s look of good solid gear.
As you can see, there were quite a lot of boats waiting to leave Bristol for a jaunt down the river, most notably the Matthew, and Bristol Packet's Bagheera.
As a pedestrian I have a few alternative routes to cross. I decided to stroll down to the outer lock gate and get back to my side of the harbour there rather than going the long way around over the Plimsoll Bridge.
In the distance you can see a lockkeeper fishing in the water with a grappling hook on the end of some blue line to see if he can figure out what the gate is fouling on.
I was expecting them to pull a shopping trolley out at any moment. They weren't managing to snag anything, though.
While I was tempted to hang around to see if they eventually pulled anything out of the way, the heat of the day was beating down pretty hard by this point and I didn't want to risk sunburn, so I headed home. As did all the boats in the lock, who returned back into Cumberland Basin and presumably eventually back to the city, refunding/rebooking their passengers.
I found out that my decision to leave had been a good one two days later, on Tuesday evening, when I happened to be on my walking commute home during another locking out, this time with the lock gates working. I asked the lock keeper about the problem, and apparently they'd tried hooking out whatever was fouling the gate for quite some time on Sunday, but eventually gave up and sent divers in on Monday, who pulled out a large section of chain-link fence that was fouling the south lock gate and got everything working again.
I'm in the habit of going over to the Tobacco Factory Market on a Sunday. I think I've walked all the routes around that way, but as a Plimsoll Bridge swing let me cross the road to the far side of Brunel Way on my return journey and I took a couple of photos of the brownfield development at the old Ashton Gate Depot site I thought I'd call it a Wander and pop some photos up.
