en.Wedoany.com Reported - National Highways has proposed a major upgrade plan for a key section of the A36 in Wiltshire. The plan aims to improve capacity on Southampton Road in Salisbury, which carries significant strategic and local traffic.

Chris Hildrup, Route Manager at National Highways, stated that opportunities for building new infrastructure are limited, and the A36 not only serves long-distance strategic traffic but also handles substantial local travel demand, necessitating research into enhancing road capacity. He revealed that the plan involves increasing the number of lanes and capacity at College Roundabout and Bourne Way Roundabout to improve traffic flow and journey reliability on this section. Hildrup added that the solution must be completed and operational by 2031, posing significant time pressure.

Ben Atwill, Lead Designer at partner WSP and one of the project's principal engineers, explained that the upgrade will involve reconfiguring College Roundabout with traffic signals, expanding its area, adding lanes to each entry and exit arm, and restoring two existing left-turn lanes, all controlled by signals. He stated that this will allow more vehicles to pass through the intersection simultaneously, reducing journey delays on the A36 and the local road network.

The upgrade requires a larger footprint, necessitating the acquisition of land from Wiltshire Council to the west and Salisbury City Council to the south. Hildrup indicated that the estimated cost of £25 million is relatively low for such works and noted that ecological issues may pose the greatest risk to the project.
