The changes by Shropshire Council also include improvements to walking and cycling routes in the town centre.
While preparatory work to prepare the area for construction will begin on Monday, the rest of the project is set to be carried out in phases. Next week's work is not likely to impact on traffic movement, Shropshire Council said. Two temporary compounds will be in place for the duration of the work. One will be based in the bus layover area in Raven Meadows, opposite Shrewsbury Bus Station, and one will be based in Frankwell Main car park.
“The town centre will very much be open for business during the work and we encourage people to continue visiting the town, but to consider using alternative routes if they can, or to use alternative modes of travel – including walking, cycling, public transport and park and ride.”
