The Gwinnett County Board of Commissioners approved two Lilburn-area road construction projects Tuesday.

Commissioners awarded a $458,029 contract to ISC Inc. for work on Miller Road from Cole Drive to Hambrick Drive. The road should have new curbs, gutters and sidewalks by next fall.

Commissioners also approved an agreement with the City of Lilburn to relocate Main Street from Lawrenceville Highway to the proposed new city hall and library at Church Street. Under the agreement, the city will pay for all preliminary engineering and land acquisition and the county will manage construction.
