A lane of Carholme Road up to the junction with Newland is closed to motorists from today until next year for a major student digs project at Viking House.
This is in addition to a week-long closure on Carholme Road west, outside the Winning Post petrol station.
The lane next to Viking House will temporarily reopen on November 21 to allow for additional Christmas traffic, but will close again on January 7 until the works are complete.
Diversions are in place for the left hand lane of Carholme Road, which is used by motorists to get onto the Brayford Way bridge.
The closure started on October 21 and will enable safe site access for construction of new student accommodation.
Viking House is being developed by Jackson & Jackson properties and will renovate a group of commercial buildings for student housing.
The development is currently in phase two after receiving planning permission from the City of Lincoln Council earlier this year.
It is being delivered by local construction company LGG Projects.
Paul Jakuc, LGG Projects, said: “The road closures are necessary safety measures that need to be put in place until construction is complete.
“Once finished the development will significantly improve the entrance to the city and meet the accommodation demands for the increasing numbers of students coming to Lincoln.
“We are working as quickly as possible to ensure minimal delays and are working closely with the highways authority to ensure alternate routes are clearly signed.
“We apologise for any inconvenience this will cause to the public and we thank them for their patience during this time.”
