The reopening of the Stoke Hammond Bypass has been scheduled for 6am on Monday, October 8.
Contractors expect to complete road markings and installation of reflective studs on the Wing-bound carriageway by Sunday, October 7, having resurfaced the five-mile length of these lanes during the past four weeks.
Mark Shaw, Buckinghamshire County Council Deputy Leader and Transport Cabinet Member, said the £4.5 million eight-week surfacing programme had been an enormous logistical and technical engineering project - one of the county’s biggest road resurfacing schemes in recent years.
Work on the bypass begun on Monday, August 13, with the resurfacing of the five-mile northbound (Milton Keynes-bound) carriageway.
Mark said: “We were aiming at a Sunday reopening, but there was a hiccup in the regular supply of surfacing material, which means we’ll be a little later with painting road markings and installing reflective studs.
“It’s in the interests of everyone’s safety that we reopen a little later than planned, and I apologise for any inconvenience.”
