Traffic Alternatives Study The High Performance Traffic Enterprise (HPTE) commissioned the Traffic Alternatives Study, a cost benefit analysis, to identify the transit priority improvement with the greatest benefit for the […]
The skewed intersection at CO 119 and Hover Street in Longmont accommodates more of the traveling public than any of the other intersections along the CO 119 corridor between Longmont and Boulder. This intersection has long been known for its precarious, hairpin-like turn movements, poor transit and pedestrian and bicycle access.
Many commuters from rural counties north and east of the City of Longmont drive through this intersection to access jobs further south and west in the corridor, near the City of Boulder. By 2040, almost one-third of the traffic traveling through this intersection will be coming from or heading back to areas outside of Boulder County.
The CO 119 and Hover Street intersection project is a grade separation of one direction of travel to facilitate safer, more efficient travel for the traveling public and the movement of freight between areas in rural Weld and Larimer Counties to job centers and critical destinations in central Boulder County. The intersection of CO 119 (also known as Ken Pratt Boulevard within Longmont) and Hover Street is a major intersection for the region and plays a vital role in the connectivity between urban and rural areas on the Front Range.
Transportation Challenges and Solutions
This area currently has a disproportionate number of crashes based on the average daily traffic (ADT), the majority of which are rear end crashes. In addition, this intersection exhibits high levels of congestion and delay. To improve these conditions and mitigate these challenges, three critical changes will be integrated into the intersection design:
- A new grade-separated tunnel under Hover Street will accommodate the westbound through movement to alleviate traffic congestion. Removing the westbound movement from the traffic signal phase allows a reallocation of signal time to the other priority traffic movements, thereby providing an acceptable Level of Service (LOS) for the existing and future conditions.
- A barrier separated bicycle and pedestrian path through the tunnel will allow bicyclists and pedestrians to cross the north leg of Hover Street safely in both directions.
- The east-bound bus stop at the CO 119 and Hover Street intersection underpass will be maintained while also facilitating a proposed regional Bus Rapid Transit (BRT) route with a bus-only queue jump lane and connected vehicle (CV) technology to support transit signal prioritization (TSP).
