Interstate 70 through Glenwood Canyon fully reopened Tuesday following that prompted weeks of lane closures and long delays for motorists.
Tracy Trulove, spokeswoman for the Colorado Department of Transportation, said the reopening is 23 days earlier than expected.
Trulove said good weather allowed crews to get ahead of schedule and make necessary repairs and complete rockfall mitigation faster than anticipated.
I-70 was fully closed for about a week after car-sized boulders early on Feb. 15.
Motorists were forced to travel with the aid of a pace car only in the eastbound lanes of the interstate in a head-to-head configuration before travel resumed in one lane in each direction.
CDOT said it paid American Civil Constructors West Coast $5 million for the emergency project.
