Upton Bypass bridge protection

Bridge protection barriers

In January 2018 we will be returning to the Upton Bypass to install new protection barriers for three bridges that cross over the road.

At the moment the piers (legs) of the A350 overbridges and Brickworks Bridge are vulnerable to severe damage if a large vehicle on the Upton Bypass were to hit them, so we plan to replace the existing steel barriers with higher concrete ones.

Because of the overall length of time the work will take, we'll be building the concrete protection in two stages - to avoid working in the summer months.

Latest news - 3 October

In preparation for us returning to the A35 Upton Bypass in January 2018, we'll be clearing vegetation in October.

Work will take place overnight on Monday 16 and Tuesday 17 October. Lane closures will be in place from 7pm to 5am between the A350 slip roads so we can safely carry out tree works.

On Wednesday 18 and Thursday 19 there'll be off-peak mobile works between 9am and 4pm for vegetation clearance.

If all goes well weather-wise we shouldn't need the Friday for the work, but we've booked the roadspace just in case!

Vegetation will be cleared from the verges as well as in an area to the north of the dual carriageway for the works compound. To utilise the same lane closures, we'll also be doing some routine maintenance; jetting and clearing the filter drains.

Our clearance work will prevent reptiles and other animals from hibernating in the area during the winter.

Bridge protection - national standards

Around eight years ago, following a change in the national standards, we started a programme of protecting bridge piers that could be demolished if they were hit by a big vehicle.

Sites protected so far include:

  • B3067, Policeman's Lane Bridge
  • Somerford Roundabout footbridge
  • A30 Shaftesbury
  • A338 bridges (as part of rebuild)
