The latest million dollar flaw at the Big Dig in Boston is adding frustration the nearly $15 billion project and its associated headaches.
Concrete road surfaces in the Central Artery tunnels that were meant to last more than thirty years are failing in less than a decade. The growing potholes and crumbling surfaces mean the roadways will have to be repaved, according to the state's highway administrator.
The team overseeing construction decided to use concrete instead of the traditional New England asphalt, despite it being ill-suited to the region's frigid temperatures. The concrete is separating from the structural elements beneath and buckling. Officials have denied that the tunnel structure itself may be compromised.
Repairs may begin as soon as June 16th.
