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: On Thursday, September 13, southbound traffic moved onto the newly completed pavement on the west side of the road. The new alignment did not affect northbound traffic. Traffic is now split onto the proper northbound and southbound lanes, but one lane in each direction remains closed and periodic shifts to the inside or outside lane will occur as additional work is completed on medians, curbs, etc. Please use caution when driving through the project area, be alert for changing conditions and obey posted speed limits.
Peña Boulevard: Paving is underway on the new on-ramp from Tower Road to westbound Peña and the bridge widening is being completed as well. The rebuilt off-ramp from westbound Peña to Tower Road opened on May 12. The new 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.
