Gas works at the Burton Road/Yarborough Crescent roundabout have been causing travel chaos for many in the city this week.
Motorists have been advised to find alternative routes after diversions and severe blockages on Yarborough Road caused confusion for drivers.
The work by gas network Cadent is part of a wider project to upgrade 1.8kns of ageing gas mains in Yarborough Crescent and Yarborough Road.
This project began on July 4 and is expected to last 16 weeks.
Work on the roundabout began on Monday and is due to be finished on Tuesday, August 21.
A Cadent spokesperson said: “We are doing our best to minimise delays but advise motorists to take an alternative route where they can and leave extra time for journeys. To aid traffic flow further, we advise motorists to pay particular attention to the signage on the approach to and when negotiating the roundabout.
“Look at the layout of the traffic management and plan which exit you need. No roads on the roundabout are closed, so every exit is available to take.
“Depending on which exit you need, the traffic management may direct you to go “the wrong way around” the roundabout or on the wrong side of traffic islands, where this is the case this is clearly signed.
“We’d like to thank people for bearing with us while we complete this essential work.
“Cadent is replacing the ageing metal gas mains with tough new plastic pipes that will last at least 80 years. The new pipes will ensure local people continue to enjoy safe and reliable gas supplies for cooking and heating until the end of the century.”
