Why does the A361 / Welsh Road Opening Date Keep Altering?

Why does the A361 / Welsh Road Opening Date Keep Altering?

We have received this explanation of why the dates keep altering:

"Currently, as you may be aware, our biggest constraint is the shallow gas main which was discovered on Welsh Road East, in the left lane on the approach to the A361 junction. Due to this shallow gas main, we cannot allow traffic over this lane until it has been diverted. This means that unfortunately, we have to align with the utilities companies works schedule in order to divert this and they have given us the indicative programme of between 21st September and late October. We are working with them to expediate this diversion however the programme unfortunately has not yet been confirmed.

"Due to the location of this shallow gas main, we currently cannot open all four roads in full without installing temporary traffic lights across the whole junction for safety reasons. The junction would not operate safely without four way traffic lights controlling the flow. This is due to the positioning of the constructed traffic splitter island on the east arm restricting traffic flow / larger vehicle turning radius across the junction.

"Installing a four way crossroads traffic light system would have the largest net negative effect on the road network, particularly the flow along the A361 as this would add a further delay in traffic flow. For this reason we need to avoid this option.

"Following the completion of the advertised weekend closure of the A361 on the 21 September Welsh Road West to Aston Le Walls will be open in full and the traffic lights removed from the A361. The west arm will then operate as intended as a give way junction. The opposing EAST arm will then be fully closed until the gas main is diverted and the road construction completed. We are working with the utility company SGN and scrutinising their programme to get the junction open as soon as we can.

"For the equestrian show we swapped the closure over so that Welsh Road east was closed, however, works to the verge had still not been complete by this point so the transferral back was necessary. If we would not have taken this action 1000+ horse boxes would have been traveling through Aston Le Walls around for the event which would have caused significant disruption. As closures come into effect over the next two weekends for north tie in, we can't open Welsh Road west whilst these closures are in place so would have to do major shifts in the traffic management to keep Welsh Road west open during the week. There wasn't the resource to gain the consents from the council to put this into force in time I'm afraid.
