The oldest section of the Suwanee Creek Greenway, from Martin Farm Road to Suwanee Elementary School, will be closed in two phases over a seven-month period for improvements.

The city plans to rehabilitate and upgrade about one-mile section of the multiuse trail. Existing asphalt and boardwalk will be demolished, and new concrete and boardwalk will be installed at widths matching newer sections of the Greenway.

The total project is expected to cost about $1.2 million. Funds will come from local sales taxes and the city’s remaining open space bond money.
