Central 70

Central 70 between I-25 and Tower Road is one of the most heavily traveled and congested highway corridors in the Denver region and the State. For the last decade, a series of improvement studies have been performed to this corridor to make the interstate safer, relieve congestion, and address aging infrastructure. Phase 1 of this redevelopment project includes:

  • Complete reconstruction of I-70 from Brighton Boulevard to I-270 including the addition of one Express Lane in each direction;
  • Removing the 50-year-old viaduct and lowering the interstate between Brighton and Colorado Boulevards;
  • Construction of a new 4-acre cover over the interstate between Clayton and Columbine Streets;
  • Widening I-70 from I-270 to Chambers Road to accommodate one Express Lane in each direction; and
  • Restriping I-70 from I-25 to Brighton Boulevard to accommodate one Express Lane in each direction.

For more information, please refer to CDOT's website to learn more about the Project.
