21-mile detour set as Hampshire road closes for repairs
A vital Hampshire road will shut for nearly six days next week, forcing drivers on a 21-mile diversion. The closure begins Tuesday at 7pm and runs until Monday at 7am to apply a surface layer prolonging Corhampton Road’s lifespan.
Bishop’s Waltham’s Corhampton Road will close entirely from 7pm on June 3 until 7am on June 9, cutting off a critical east-west link through the town centre. Hampshire County Council confirmed the closure is part of a £4.2 million surface treatment programme to extend the road’s durability by up to 10 years, according to internal estimates.
Drivers will be directed via the A32, M27 and A31, adding at least 40 minutes to journeys between Bishop’s Waltham and Fareham. Local hauliers warned the detour risks delays at peak times, particularly near the M27 interchange at Portswood. One logistics manager based in Whiteley said, “We’re rerouting three trucks daily; that’s six extra hours on the road.”
📋 By The Numbers
- £4.2 million — Total budget for Hampshire’s 2026 surface treatment rollout
- 10 years — Expected extension to Corhampton Road’s usable life
- 6 days — Duration of full closure
- 40 minutes — Minimum added journey time via diversion
Council leaders defended the closure schedule, stating night-time works were ruled out due to noise restrictions near residential streets. A spokesperson said, “We consulted residents in March and received 87% support for the June timing.” Residents received leaflets via door drops in April detailing diversion signage and bus route changes.
| Route Segment | Distance | Estimated Delay |
|---|---|---|
| Bishop’s Waltham to Portswood | 14 miles | 25 minutes |
| Portswood to Fareham | 7 miles | 15 minutes |
The county council has arranged temporary bus stops near the closure zone and added extra services on the 86 route to mitigate disruption for pupils at Henry Cort Community College. Headteacher Sarah Whitmore said, “We’ve briefed students on alternative routes and arranged supervised walking zones near the diversion start.”
