COMMUNITY BENEFIT: The US 40 Improvements Project improved safety, reduced traffic congestion and increased access to both existing businesses and new business development.

The work was part of a coordinated program of strategic projects near the Dayton International Airport that proactively addresses growth in traffic expected over the next several decades to ensure continuous and efficient traffic flow for all who travel through this area. This has provided 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 addressed roadway design issues while adding capacity. It included:

  • Construction of 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.
  • Tapered the roadway from Union Airpark Boulevard back to two lanes to the west.
  • Reconstructed the ramps to Airport Access Road to meet modern design standards and improve the interchange’s safety.
  • Upgraded traffic signals at the interchange of US 40 and Airport Access Road.

COMPLETION: The project was completed in 2022 and the occasion was marked with a celebratory ribbon cutting ceremony with the regional partners as pictured below. Learn more.
