New 23rd Avenue Off-Ramp Opens to Traffic/Colorado Loses Corridor Funding Bid/Rubberized Asphalt Project Moves Forward
CDOT reopened the 23rd Avenue off-ramp from I-25 to traffic in late August. The rehabed interchange will help alleviate traffic congestion near Invesco Field.
CDOT Opens New I-25 Off-Ramp at 23rd Avenue
The Colorado Department of Transportation completed the new ramp from southbound I-25 to 23rd Avenue in late August to help alleviate traffic congestion near Invesco Field. Work is continuing to improve the I-25/Speer Boulevard interchange just north of the stadium.
The new off-ramp to 23rd Avenue carries traffic over the on-ramp from eastbound Speer Boulevard to southbound I-25 and requires motorists to exit southbound I-25 approximately 1,100 ft north of the current configuration.
In addition to the new 23rd Avenue off-ramp, the project eliminated the Speer Boulevard loop ramps on the west side of I-25. Flatiron Constructors Inc. was the contractor for the $6.6-million project, which was funded primarily by the city of Denver with help from the Federal Highway Administration and CDOT.
Colorado’s U.S. 36 Corridor Proposal Rejected
Colorado was notified in August that its U.S. 36 corridor proposal was not selected as one of the five states that will receive funds under the U.S. Department of Transportation’s Urban Partnership program, which provides federal investments of up to $1.1 billion to reduce traffic tie-ups in America’s most congested cities.
The $234.5-million proposal would have added new multi-modal express lanes along the 18-mi. stretch of U.S. 36 between I-25 and Boulder, using congestion-priced tolling to manage traffic. It also included new technological components for traffic and incident management, traveler information and teleworking program expansion as well as a new managed lane to provide a state-of-the-art Bus Rapid Transit system.
The U.S. 36 Mayors and Commissioners Coalition—made up of members from the city of Westminster, city and county of Broomfield, city of Louisville, town of Superior, city of Boulder, Boulder County, and the city and county of Denver—submitted the application in April for federal funding for the crowded U.S. 36 corridor between I-25 to the east and Foothills Parkway in Boulder on the west. Supporting partners include CDOT, Regional Transportation District, 36 Commuting Solutions, city and county of Denver and the governor’s office.
Regardless of the proposal, work will continue on U.S. 36.
Rubberized Asphalt Pilot Project Nears Completion
The first two phases of the rubberized asphalt project planned by the city of Colorado Springs with Nolte Associates Inc. are complete.
These two phases tested Terminal Blend Tire Rubber Asphalt on a stretch of Union Blvd from Austin Bluffs to Constitution as part of the city’s effort to find new technologies that would improve and prolong the life of its roadways.
In 2005, Nolte and representatives from the city of Colorado Springs began researching the use of tire rubberized asphalt. Safety statistics, such as skid resistance and visibility in inclement weather, are expected to improve with the drainage afforded by the permeable friction course graded asphalt mix. Due to the success of the project, phases three and four have already begun and the paving project continues down Union Boulevard.
SEMA Completes Repairs to Damaged G.J. Bridge
SEMA Construction Inc. of Englewood has completed work on permanent repairs to the Road 26.5 bridge on I-70 near Grand Junction. The bridge was damaged on Aug. 15 when a semi smashed into and damaged the bridge column.
SEMA’s crews removed both Pier 4 columns, replacing them with reinforced concrete columns and then installed new guardrail and barrier. The $319,349 project was completed in about 20 days.
