A section of Canwick Road in Lincoln will be closed and additional traffic restrictions will be in place during two weekends.
The closure and restrictions will be in place between March 20 and 23 and then again between March 28 and 29.
As part of £4.5 million works to improve Canwick Road and install another lane work to install a large 600mm diameter drainage pipe under the road will mean traffic will be restricted throughout the weekends.
Work will start at 6pm on Friday, March 20, when Canwick Road between South Park Avenue and South Park will be reduced to one lane using temporary traffic signals.
The single lane is in place until 6pm on Saturday, March 21 when Canwick Road between South Park Avenue and Washingborough Road will be fully closed to all traffic until 5am on Monday, March 23.
A signed diversion route will be in place via South Park Avenue, Cross O Cliff Hill, Canwick Avenue and back on to Canwick Road (and vice versa).
Lincolnshire County Council say access will be maintained for residents on South Park from a southerly direction only.
Traffic movements will revert back to the existing arrangements on March 23 until the weekend of March 28 and 19, when exactly the same restrictions will apply in order to complete the works.
Alan Aistrup, special projects manager said: “We apologise for any inconvenience these arrangements will cause, however they are essential to ensure the safety of the workforce and the travelling public. They will also enable us to complete these vital works in the shortest possible time, with the minimum of disruption and delay.
“We recognise that the Lincoln 10k road race is taking place on Sunday 22 March, however the route is in uphill Lincoln. We have advised the organisers of the closure and recommend that competitors and spectators who are travelling from the south use the A15 and A46 to access the event and to allow extra time for their journey.”
