The A49 both directions will be closed with the above timings, at Bayston Hill/South of Shrewsbury, trust me the diversion route at Church Stretton over to Much Wenlock is to be missed, avoid it. Its up too you 
From HA,
“While the overnight closures are in place, northbound traffic will be diverted from the A49/B4371 junction at Church Stretton onto the B4371 eastbound. At the Much Wenlock junction of the B4371/A458, traffic should take the A458 northbound, and continue to its junction with A5.”
“Southbound traffic will be diverted from the A49/A5 Dobbies Island onto the A5 eastbound. Traffic should then leave the A5 at its junction with A458 and take the A458 southbound to its junction with the B4368 at Morville. Traffic should then take the B4368 westbound and rejoin A49 at Craven Arms”
