Drivers on A46 at Whisby warned over 14-month roadworks
Drivers in Lincolnshire are being urged to allow extra time for their journeys as 14 months of work to a major route begins.
Part of the A46 Lincoln Bypass near Whisby is being made into a dual carriageway as part of plans for the new Teal Park business development.
Speed restrictions of 40mph will be put in place later in June and temporary traffic lights will be in use.
The work will cost about £10m and should be completed by August 2012.
Paul Coatup from Lincolnshire County Council's highways department said the disruption would be worth it in the long run.
"There's a 40mph speed limit for safety and I would imagine that very few people would be able to drive at more than 40mph through the works, most of the time," he said.
"This is massive investment in this part of the city at a time when everyone is crying out for employment and new developments."
