Network Rail is advising motorists in Corby that safety work to Cottingham Road bridge will now complete on Friday, 3 May.
A partial road closure is currently in place to enable Network Rail workers to remove the current crash barrier to strengthen it, before reinstalling it an in increased height.
Work was scheduled to begin on Monday, 4 March and complete on Saturday, 27 April. However, work on the project, as well as the partial road closure, did not begin until Monday, 11 March meaning the completion date has moved back a week. The road will fully reopen by the evening of Friday, 3 May. The duration of the project remains six weeks.
Gavin Crook, Principal Programme Sponsor for Network Rail, said: “We would like to apologise for the amended completion date of the project as we know that this will cause some disruption to motorists. The work has been done under a partial road closure to keep disruption to a minimum.
“This is the final piece of work to Cottingham Road bridge as part of the Midland Main Line Upgrade and we would like to thank all those who have been impacted by this for their patience.”
