Mousetrap, Highway interchange in northern Denver, United States
Mousetrap is a highway interchange in northern Denver where Interstate 25 and Interstate 70 meet. The structure consists of multiple levels with curved ramps that connect the two major routes and allow traffic to flow between them.
The original connection was built in 1951 to link local roads well before the Interstate Highway System was established. Beginning in 1987, a complete reconstruction modernized the structure and improved how traffic moved through it.
A radio traffic reporter named the interchange in the 1960s after noticing how its tangled ramps resembled a device designed to trap mice. The name stuck and remains how locals refer to this complex highway junction today.
This junction experiences heavy traffic flow throughout the day, so expect congestion during rush hours and plan extra time when traveling through. For anyone wanting to view or photograph the structure, nearby overpasses and elevated areas offer the clearest vantage points.
An overturned truck carrying naval weapons created an unusual crisis in 1984 that forced nearby area evacuations. This incident exposed weaknesses in the old design and became the catalyst for the major renovation work that followed.
