The only intermediate freeway interchange on Peña Boulevard is a full cloverleaf interchange with the tolled E-470, which provides an alternate north–south route to I-25 for travelers wishing to bypass on the eastern side of Metropolitan Denver area. E-470 also intersects I-70 and has a higher speed limit than Peña Boulevard. The interchange with E-470 is the easternmost exit before entering Denver International Airport. Once inside airport grounds, the freeway intersects the car rental return area, and connects to the parking garages and terminal access roads.
