A new road layout is set to be unveiled tomorrow (Friday) marking "another significant milestone" towards the construction of the £126.75m Gull Wing bridge in Lowestoft.

Motorists had faced delays ever since parts of three busy roads had been temporarily closed in March amid the continuing third crossing works.

With work taking place on sections of three roads on the northern side of Lake Lothing, it has seen works carried out on Denmark Road, Peto Way and the southern end of Rotterdam Road since March 1.

As the work has been carried out "between the Wickes roundabout and 268 Denmark Road" to allow "for the building of a new northern roundabout and road alignment for new bridge construction," the project was due to be completed by August 31.

But with highway construction taking longer than expected, leading building and civil engineering contractor Farrans Construction - which is overseeing work on the £126.75m Gull Wing bridge on behalf of Suffolk County Council - applied to extend the closure of Denmark Road until October 31 following the set back.

It means the long-awaited third crossing is now due to be opened next year.

A Gull Wing bridge spokesman said: "The current road closure on Denmark Road/Peto Way/Rotterdam Road in Lowestoft is due be lifted on Friday, October 20 at 11am.

"The new road layout will open for traffic from all directions at this time.

"Whilst the road reopens for traffic, we will continue to construct the northern approach of the Gull Wing Bridge, attenuation ponds and surrounding public realm over the next few months.

"In order to carry out these remaining works safely and efficiently, sections of the new southern footpaths will remain temporarily closed for pedestrians and non-motorised users.

"Plan 1 indicates the open and closed footpaths and routes for pedestrians and non-motorised users.

"There are three crossing points for pedestrians and non-motorised users which can be used whilst these temporary measures are in place on Peto Way, Rotterdam Road and Denmark Road."
