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.
New Ramp Opening: Oct. 29, 2018
Officials from all the project partners were joined by Congressman Ed Perlmutter (CO-7) and others to celebrate the opening of the new Tower-Peña on-ramp with a ribbon-cutting ceremony on October 29. The ramp officially opened to traffic just after the ceremony, allowing drivers quick and convenient access to westbound Peña Boulevard from Tower Road for the first time. The four new lanes of Tower Road constructed through the project opened to traffic on November 20.
Drivers may still encounter periodic delays, lane closures and traffic shifts until construction completes in December. Please use caution when driving through the project area, be alert for changing conditions and obey posted speed limits.
Tower Road: All four newly-widened lanes of Tower Road opened to traffic on November 20, bringing an end to major traffic impacts from the project and improving conditions for commuters. Midday lane closures, traffic shifts and minor delays may still occur during finishing work until the project is fully complete in December.
Peña Boulevard: The new on-ramp from Tower Road to westbound Peña Boulevard opened to traffic on Monday, Oct. 29. The rebuilt off-ramp from westbound Peña to Tower Road opened in May. The new intersection and traffic signal where the westbound Peña ramps meet Tower Road is now fully functional.

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.
