Interstate 70 reopened to traffic around 3 p.m. Thursday for the first time in four days through Glenwood Canyon, with CDOT clearing one lane in each direction through the area damaged by a rockslide early Monday morning.

The dirt is starting to move in the $40.1 million design-build reconstruction of four miles along Hampden Avenue, starting at the east end of the corridor with replacement of the bridge over Federal Boulevard.

The Colorado Department of Transportation says it will reopen two lanes of Interstate 70 through the damaged rockslide area in Glenwood Canyon by the end of the day Thursday after geologists blasted down a huge boulder and surrounding rock that threatened to fall onto the highway.

CDOT says the current plan for closed I-70 through Glenwood Canyon is to repair a large hole in the eastbound structure, then reopen it to one lane in each direction. That would allow traffic to resume while repairs are made on the larger hole in the westbound structure.

If Sen. Jim Bunning had not balked at the end of his far-from-perfect game on the floor of the U.S. Senate, the Colorado Department of Transportation and the team of contractors out in the field on numerous federal-aid highway projects stood to lose an average of $1.76 million in reimbursement per workday.

Matt Salek, webmaster of the Highways of Colorado site and blogger on transportation issues at Milepost 61, decided to go skiing on Sunday and leave early to avoid the traffic jams. Didn’t work. The early jamming wasn’t at the Eisenhower Tunnel, which gets all the notice, but at the Twin Tunnels in Idaho Springs. Read about it here.

The beefed-up late fees that came with last year’s FASTER bill made a lot of procrastinating motorists angry but they have also had a much quieter and positive effect. More and more people are registering their vehicles on time rather than letting their expired registrations lag.

The Denver Post reports that Sens. Chris Romer, D-Denver, and Dan Gibbs, D-Silverthorne, intend to introduce legislation that would place movable concrete barriers on westbound Interstate 70 on weekend afternoons, temporarily using the inside lane for a third eastbound lane along one of the roadway’s most snarled segments. Another bill would restrict trucks to the right lane during congested hours. They estimate the extra eastbound lane could halve drive times from Georgetown to Idaho Springs.

CDOT stopped eastbound traffic from entering the Eisenhower-Johnson Memorial Tunnels Sunday afternoon and evening due to heavy traffic backing up into the tunnel. When this occurs, CDOT uses 20-minute traffic stops on the west side, which it calls “metering,” in order to prevent vehicles from standing idle inside the tunnel.
