Demolition, site work, paving and new construction of a bridge / tunnel in Thornton, Colorado. Conceptual plans call for the demolition of a bridge / tunnel; for the construction of a bridge / tunnel; for site work for a bridge / tunnel; and for paving for a bridge / tunnel.

This project would replace the existing crossing with dual 8' x 8' concrete box culvert at Huron St to convey the 100-year event and replace concrete channel from Huron St to Thornton Parkway with grass lined channel, including drop structures. This work is identified in the Mile High Flood District's Niver Creek Major Drainageways plan. The preliminary design will evaluate the feasibility and cost of a pedestrian underpass alternative. Funding for the additional cost of a pedestrian underpass would need to come from non-stormwater funds. The initial year funding is for beginning design. MHFD does a 4-year CIP look ahead, so 2027 will not be on their program this year. The city will apply for 2027 funding when that becomes available. As of October 24, 2024, this project is included in the city's 2024-2028 Capital Improvement Program (CIP) *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
