Forth Replacement Crossing

Re: Forth Replacement Crossing
I remember having to increase my velocity slightly in an old diesel car at the end of the A90, there is a bit of a downhill, to try and build up momentum for the uphill section of the start of the M90.

Re: Forth Replacement Crossing
Why is traffic management necessary so soon? This is an off-line upgrade, and apparently work has not even started - r the new bridge itself will, presumably, be the biggest part of the job. It must be years before the approaches to the new bridge need to be started, and even longer before they are tied in to the existing roads.
Re: Forth Replacement Crossing
Maybe the thinking is that they'll be able to improve traffic flow (in theory) on the existing bridge approach in the mean time, which is not necessarily a bad thing if it can provide more reliable journey times.

Re: Forth Replacement Crossing
It won't help traffic flow northbound over the FRB if there are two streams of fast-moving traffic from the M9 spur and the A90 coming up to six miles of slow-moving traffic - a 40mph limit under SPECS will result in a traffic flow of 35mph at best as drivers err on the side of caution.orudge wrote:Maybe the thinking is that they'll be able to improve traffic flow (in theory) on the existing bridge approach in the mean time, which is not necessarily a bad thing if it can provide more reliable journey times.

And the occasional driver doing 60mph, slowing to 40 as they drive past the cameras

Re: Forth Replacement Crossing
From here:When government documents describe a road as "motorway standard", it is not always safe to deduce from that either that it will be officially a motorway, or that it won't.
So I think we can finally establish, as Wrinkly suggested, that the new bridge will be motorway.The proposed new cable-stayed bridge will have three slender single column towers and will be 2.7km long, including approach viaducts. The road carried by the bridge will be designated as a motorway.
Does look like there is still the inexplicable section of A road at the southern end though. Perhaps they will change their minds at a later date.

Re: Forth Replacement Crossing
It's for the installation of the Intelligent Transport System (ATM) gantries on the existing A90, which will be a part of the overall scheme.t1(M) wrote:Why is traffic management necessary so soon?

Re: Forth Replacement Crossing
"Coast" on BBC2 just now has had an excellent piece on the structural problems with the existing bridge. It's a repeat, so it's out of date regarding recent developments, but a good non-technical explanation and some vertigo inducing film.

What if I want to take a tandem across the firth on New Year's Day?
Re: Forth Replacement Crossing
Could really do with ATM on the south side as well - all the way from Newbridge and Cramond Brig out to the bridge. Enforced limits might help the flow of traffic a bit
this is a small sig to not get in your way

I had someone fly past me earlier then slam on their breaks and drive at 35 through the works. Thankfully overtaking them again was an easy feat.Trebeck wrote:And the occasional driver doing 60mph, slowing to 40 as they drive past the cameras
Are we getting hard shoulder running with this project or just variable speed limits on the current running lanes?
Re: Forth Replacement Crossing
Surely, given the short distance between the end of the M9 spur and the supposed start of the new bridge carriageway, it will be continuous motorway?
Looking on OSM here, there would be what - 600 yards or so of gap between the two stretches.
Likely that we'll see an M90 joined to the rest of the network?

Re: Forth Replacement Crossing
Would have made sense at the time of extending the M9 spur to have redirected it to the left of Dundas Castle.stu531 wrote:Surely, given the short distance between the end of the M9 spur and the supposed start of the new bridge carriageway, it will be continuous motorway?

Traffic from the M8 will have to follow a bit of an S shape to get to the new bridge.

The whole arrangement of roads south of the Forth Road Bridge looks rather odd, especially the dogleg in the A90-A8000Trebeck wrote:Would have made sense at the time of extending the M9 spur to have redirected it to the left of Dundas Castle.

Re: Forth Replacement Crossing
But the M9 spur was built to connect to the existing bridge, the second crossing wasn't confirmed to be going ahead at the time.Trebeck wrote:Would have made sense at the time of extending the M9 spur to have redirected it to the left of Dundas Castle.

One of the proposed links to the FRC did included a new motorway to link to the M9 at a new junction further west than 1a on a more direct route.
The A8000 doesn't exist any more, some time after being superseded by the M9 spur extension it was reverted to B800 as it now only a local route.booshank wrote:The whole arrangement of roads south of the Forth Road Bridge looks rather odd, especially the dogleg in the A90-A8000
The route of the M9 spur has to fit between M9 J1 and Echline Junction on the A90 and avoid Kirkliston, the slightly less than direct route is the only way this could be achieved.

Re: Forth Replacement Crossing
It also follows the railway, meaning less severance of rural land. It does look stupid on a map though...Glen wrote:But the M9 spur was built to connect to the existing bridge, the second crossing wasn't confirmed to be going ahead at the time.Trebeck wrote:Would have made sense at the time of extending the M9 spur to have redirected it to the left of Dundas Castle.
