Crews changing southbound Colorado Boulevard entry to eastbound I-70

April 18, 2019 - Motorists will access eastbound I-70 differently from southbound Colorado Boulevard

DENVER—Starting Friday, April 19, travelers trying to access eastbound I-70 from southbound Colorado Boulevard will use a signalized left turn to enter the interstate. Crews will permanently close the right-hand loop.

Colorado Boulevard

This change in access provides a safer entryway to the interstate and is the first step in rebuilding the Colorado Boulevard/I-70 interchange as part of the Central 70 Project. Over the past few decades, new interchange designs have been implemented with less-curved exit ramps to reduce congestion and improve safety.

Signs will guide motorists well ahead of the new entrance ramp. The construction schedule is weather dependent and subject to change.
