About the Project
Commerce City is working with the City & County of Denver, Denver International Airport and the E-470 Public Highway Authority to build the much-anticipated on-ramp from Tower Road to westbound Peña Boulevard.
The project also involves rebuilding the existing off-ramp from westbound Peña onto Tower and widening Tower Road to four lanes from the Commerce City-Denver border (E. 80th Avenue) to just south of the Tower-Peña interchange. The widening in this project picks up where Commerce City’s recently completed widening project left off, making Tower Road four lanes wide from E. 104th Avenue all the way to Interstate 70.
No full closures are expected during the project, but drivers on both Tower Road and westbound Peña Boulevard may encounter periodic delays, lane closures and traffic shifts during construction.
Tower Road: A new traffic alignment is scheduled to take effect Saturday, May 12, with traffic in both directions shifting from the existing southbound lanes to the newly-constructed northbound lanes. The partial shift will be located just north of the new intersection with the rebuilt off-ramp until paving is complete on the new northbound lanes through the northern part of the project.
Peña Boulevard: The rebuilt off-ramp from westbound Peña to Tower Road is scheduled to open Saturday, May 12. The rebuilt version of the ramp runs closer to Peña Boulevard to align with the new westbound on-ramp that will soon be constructed. Because of this, the intersection and traffic signal where the ramp meets Tower Road is now located south of the previous intersection.

Expected Completion: Late 2018
Total Project Budget: $12.1 million (split between Denver, E-470 and Commerce City)

The project became a reality through a series of intergovernmental agreements between Commerce City, E-470 and the City & County of Denver, along with approvals from Denver International Airport and the Federal Aviation Administration. These long-standing agreements allow Commerce City to oversee design and construction of the project, with E-470 contributing the cost of on-ramp construction and Denver paying for the Tower Road widening portion. Denver will also handle maintenance for the new infrastructure being built, since the entire project takes place inside Denver city limits.
