T.R. Hughes Ramp to Westbound I-70 Permanently Closed, Relocated Ramp to Reopen Later this Year

The T.R. Hughes ramp to westbound I-70 closed at 2 p.m. Friday, Aug. 3 as part of the I-70 and Route K Traffic Flow Improvement project.  The ramp will not reopen in its current location.  A new, relocated ramp will open later this year. 

The ramp closure was scheduled for later in the project but was closed early for safety due to the short merge for drivers coming onto westbound I-70.

Drivers can detour around the ramp closure by either taking the I-70 North Outer Road (East Terra) to Route K or taking Mexico to Route K.  Please allow yourself extra time while using these detour routes as the extra traffic could cause delays.
