COMMUNITY BENEFIT: The US 40 Improvements Project will improve safety, reduce traffic congestion and increase access to both existing businesses and new business development.

This work is part of a coordinated program of strategic projects near the Dayton International Airport that proactively address growth in traffic expected over the next several decades to ensure continuous and efficient traffic flow for all who travel through this area. At the same time, they provide significant economic benefits by making development more attractive and competitive in the area, resulting in the potential for an increased local tax base.

DETAILED SCOPE: The project addresses roadway design issues while adding capacity. It includes:

  • Constructing a new continuous five-lane section of US 40 from just west of Union Airpark Boulevard to Airport Access Road, with two through lanes in each direction and a center left turn lane.
  • Tapering the roadway from Union Airpark Boulevard back to two lanes to the west.
  • Reconstructing the ramps to Airport Access Road to meet modern design standards and improve the interchange‚Äôs safety.
  • Upgrading traffic signals at the interchange of US 40 and Airport Access Road.
