Gwinnett Commissioners on Tuesday approved a $31.8 million agreement with C.W. Matthews Contracting Company for widening 3.7 miles of Ga. 20, from Peachtree Industrial Boulevard to the Chattahoochee River on the western edge of the county.

The important thoroughfare, which serves about 30,000 cars every weekday, will expand to four lanes in each direction from the current two. The project, which had been estimated to cost $33.7 million, is being funded by the state.

The improvements also include a 44-foot grass median, 16-foot shoulders, curbs and gutters on the outside pavement edges, and five-foot concrete sidewalks on both sides of the roadway. The state previously spent about $30 million for rights of way for the road expansion.

The county will be responsible for the cost of inspection of the construction and materials, which is expected to run about $2.5 million.
