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 traffic shift placed in early January moved one lane in each direction onto the western lanes of Tower at the Peña interchange. This allows widening work to take place on the eastern lanes (which typically carry northbound traffic). The current shift and lower speed limit will be in place until the summer.
Peña Boulevard: Starting in February, both lanes of westbound Peña were shifted slightly to the left and the right shoulder was closed to allow space for bridge widening work for the new on-ramp. The speed limit decreased from the normal 65 mph down to 55 mph. The lane shift will remain into the summer months.

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.
