Overnight work is to be carried out to install a gas main at Tollbar Island from tomorrow (Tuesday).
Lane closures will be in place between 8pm and 6am at the Tollbar Island and the A45 London Road to allow the installation of a new gas main pipe by National Grid.
The excavation work across sections of Tollbar roundabout will take around five weeks to complete.
Project manager for the Highways Agency, Paul Nagra, said: “We continue to be grateful to road users for their ongoing patience during these important works.
“This essential work can only be done overnight as we need to put lane closures near Tollbar roundabout. We avoid doing this type of work during the day, when traffic is a lot busier, as it would cause far too much disruption to road users.
“Although the roundabout will remain open, we still advise motorists to allow extra time for their journeys.”
When completed, the A45/A46 Tollbar End scheme will improve capacity, journey times and safety.
Around 45 percent of traffic will be taken from the Tollbar roundabout onto the new underpass. Access to local businesses and Coventry Airport will also be improved, as will pedestrian access at the roundabout.
