There is a very strong argument that level crossing removals should look at wider scale traffic rerouting than just one side of the fence to the other. In a town centre this is multiplied by any strategic objective to reduce motor traffic in the town centre area itself.
Torbay Borough Council, under a brief spell of Lib Dem control, partially closed Torbay Road to motor traffic as part of such a rethink. This street crosses the railway and connects the bus and rail stations and town centre to the seafront and beach. It's very busy with pedestrians, especially in the summer, and is lined with tourist shops, cafes, fruit machine arcades and a massive Wetherspoons. The pedestrian scheme would have virtually eliminated vehicular traffic over the railway, with only limited delivery and emergency services access retained. It would also have included a conversion of a redundant left turn lane on the west side to a bus lane and stop so north to south buses could briefly drop off on the way to the bus station which requires a further 1/4 mile circuit of the gyratory through two light controlled junctions to reach the stand a few metres from where they just passed right in front of the rail station. TBC had surveyed the general public to justify the measures, which had shown large-scale support. As soon as the plans became more concrete with an initial trial of the ideas however, traders and others began a strong campaign of opposition. Then, when Conservatives regained power shortly after, it was the first thing they reversed, immediately reopening the road fully to all traffic.
There is another means of crossing the railway about 600m to the north at Lower Polsham Road. This is a narrow one way lane from west to east crossing the tracks via a 4m height-limited underbridge. The whole area either side of the railway and out to the modern seafront along this stretch is extremely low-lying, being former salt marshes reclaimed in the Victorian era, so going under the railway is always likely to be challenging. A scheme is in development for strengthened sea defenses. There is a park alongside the railway between Torbay Rd and Lower Polsham Rd through which a notional new road might be constructed without demolition, passing over the railway, then descending on the east side in an area where some large car parking structures are currently being demolished. I can't see it ever being acceptable to despoil such a pleasant, popular open space as Victoria Park however. Maybe they could have got away with it in the 1970s...
BR attempted to close Sands Rd crossing again, I think in the 1980s when resignalling was in development. The owner of the mini supermarket on the corner of Sands Rd and Dartmouth Rd, on the west side of the railway, was most strident in opposition to the proposal, claiming it would affect their trade from people on the seafront crossing the line.
