Drivers using the M6 in Lancaster are being advised of up to five overnight closures as part of ongoing works for the Heysham to M6 Link Road.
Starting Monday July 20, the motorway will close at 10pm and re-open by 5am the following morning.
The closures are needed for the removal of a section of the Foundry Lane overbridge to allow the extension to be constructed.
Foundry Lane bridge carries traffic to Halton from Kellet Lane. Foundry Lane itself closed to through traffic on Monday June 29.
The current bridge is being extended to accommodate the new northbound sliproads of junction 34 onto the M6 underneath.
Diversion signs will be erected on the M6 prior to junction 34 (northbound) and junction 35 (southbound), its important drivers familiarise themselves with alternative routes, and plan their journeys ahead.
During the closure between junction 34 and 35 of the M6 all traffic will be diverted along the A6.
Southbound traffic on the M6 will exit at junction 35 and will be diverted on the A6 via Carnforth, Bolton-le-Sands, Slyne, Skerton and Lancaster.
They will be guided to re-join the M6 at junction 34.
Northbound traffic on the M6 will exit at junction 34 and will be diverted on the A6 via Lancaster, Skerton, Slyne, Bolton-le-Sands, and Carnforth. They will be guided to re-join the M6 at junction 35.
Costain Project Director Andrew Langley said: “We’ve provisionally booked five overnight closures from Monday 20th to Friday 25th as we will aim to complete the task of removing a section of the bridge section as quickly and as safely as possible.
As with most crane and bridge lifts conditions on the night or nights will impact on the operations. Once the work is completed we’ll remove traffic management, and cancel any remaining closures not required.
