The Roswell City Council has approved applying for a $2 million federal grant from the Atlanta Regional Commission to fund a proposed pedestrian bridge across the Chattahoochee River, a joint project with Sandy Springs.

The bridge would be built next to the Roswell Road (Ga. 9) highway crossing of the Chattahoochee. It received a congressional earmark more than 10 years ago, but due to increasing costs the earmark no longer is sufficient to pay for the project, staff said in a report to the council.

The $2 million in additional federal funds would close the funding gap, staff said. Roswell and Sandy Springs each would have to provide $250,000 in matching funds, or $500,000 total.

“The project is currently in the design phase, and the city of Sandy Springs is working to acquire right-of-way on the south bank of the river,” staff said. “Environmental permitting is expected to be complete in the next 18-24 months. Construction is estimated to occur in the next 24-36 months.”
