Contractors are trying to counteract tailbacks that have been building over the New Bridge in connection with the Mayfield Road junction improvement works.
Motorists have been complaining about the long queues building up on all four approaches due to temporary traffic lights.
One motorist said: “I was stuck there for 40 minutes one morning.
“The problem I had were people running the red lights, obviously they got sick of waiting.
“The lads working there were trying to keep all in order but it’s going to be a pain.”
The lights are being manually controlled by the workmen but are being removed each night reverting to the original lights system.
North Yorkshire County Council has said that this will also be the case for the forthcoming weekend.
Cllr Joe Plant said: “These are major works and some delays at the temporary lights will be inevitable.
“We know there have been some issues with queues and so additional contractors are on hand to do everything possible to maximise traffic flow.”
This week the works have included the installation of ducting across the carriageways.
All traffic routes have remain accessible, though the section of the junction that filters left from Mayfield Road to the A174 in the direction of Whitby town centre, has been closed but people can still make the left turn.
Contractors also visited St Hilda’s Primary and Airy Hill Primary to teach young people about health and safety issues on construction sites and announce a competition for the design of a safety poster.
The new junction work includes an intelligent signalling system with capabilities to detect vehicle queues and pedestrians, new traffic islands which will be built for pedestrians to cross more safely.
