The US 278 corridor improvements project includes replacement of the structurally deficient eastbound Mackay Creek Bridge.
A public meeting on the project was held last week to set out the six 'reasonable alternatives' - plus a 'no build' option - picked from the original 17 variations that were considered. A month-long public consultation process was also launched.
The purpose of the project is to address structural deficiencies at the existing eastbound Mackay Creek bridge, to increase capacity and reduce congestion along US 278 from Moss Creek Drive to Spanish Wells Road. The corridor as a whole is being examined; potential improvements may include replacing the three other bridges along the route.
South Carolina Department of Transportation has estimated that the cost would be US$240 million to replace all four bridges in the corridor with one additional lane in each direction.
It aims to identify the preferred option in late 2020.
