Raised section of the seven-lane expressway needs £26 million investment to fix it to make the 40-year-old carriageway safe.
Birmingham’s Aston Expressway – used by 90,000 motorists a day – is at “considerable” risk of collapsing, according to an official report.
A Greater Birmingham and Solihull Local Enterprise Partnership (GBSLEP) document reveals the raised section of the seven-lane expressway, which links to Spaghetti Junction, needs massive investment to fix it.
The authority estimates £26 million of repairs are required to make the 40-year-old carriageway safe.
The severity of the situation was highlighted by a £2.63 million engineering survey which revealed the full extent of decay along the primary route into Birmingham city centre.
The GBSLEP is now bidding for Government funding to carry out repairs to the route, also known as the Tame Valley Viaduct.
But council highways engineers warn that if strengthening work is not carried out soon they will need to introduce weight restrictions.
They admit the knock-on effect for the region’s road and motorway network could be catastrophic.
