Construction is underway on the South 320th Preservation Project, an asphalt overlay of South 320th Street between 11th Place South and Interstate 5.

Work includes ADA upgrades to impacted ramps and push buttons, replacement of vehicle loop detection with video detection at 25th Avenue South, pavement repairs, surface grinding, asphalt overlay and striping.

The project work recently began and is expected to be completed in early July.

Total cost for the project is estimated at $1.6 million.

Funding for the project is through a grant from the Federal Highway Administration of $1.1 million and city funds.
