Repair work on the 36 year old Spahetti Junction in Birmingham will start next week as the Highways Agency start work on a £4.1 million scheme to repair the concrete columns and supporting crossbeams.
The 17-month project to reinforce eight bridge deck supports and several columns at junction 6 of the M6 is will help to maintain Birmingham's iconic motorway interchange.
Spaghetti Junction was opened 36 years ago this month and is used by over 160,000 vehicles every day.
Highways Agency project sponsor, Moreblessing Pedhuru said:
"The programme of repairs will help to ensure the Spaghetti Junction slip roads supported by these columns continue to provide a safe route for drivers, and doing the work now will prevent further deterioration and more costly repairs in the future.
"We will install steelwork to support the carriageway whilst the repairs are being carried out. The road markings will be changed on the approach to and at the roundabout to maintain traffic flows, and a reduced speed limit will be in place for the duration of the repairs."
The M6 motorway carriageway will not be affected by the work as work is taking place below the bridge deck.
