Projects | 144th Ave Bridge

The Adams County bridge was destroyed by a major flood, cutting off daily access for nearly 1,000 vehicles and essential agricultural and freight movement.

The county selected the prefabricated InQuik® integral bridge system to deliver a permanent, flood‑resilient structure quickly and cost‑effectively.The project was completed in under six months for $2 million, saving $3 million and reducing man‑hours by 90% compared to traditional construction.

Key project points

Resilient
The new bridge uses an integral, cast‑in‑place design with a larger clear‑span to withstand future floods.

Efficient
Prefabricated InQuik® components enabled rapid installation, reducing construction time from a year to under six months.

Cost-Saving
The project was delivered for $2 million instead of the original $5 million estimate, saving the county $3 million.

Lightweight
InQuik® deck panels contain reinforcing steel and formwork only, making them easy to lift and install with minimal equipment.

Modular
The bridge required only seven picks including two abutments and five deck panels, streamlining installation and reducing man‑hours from 3000 to 300.

The location

The bridge sits in Adams County, Colorado, serving nearly 1,000 vehicles daily and connecting rural residents, farms, and freight routes.

‍

The surrounding area includes agricultural land and narrow dirt roads that cannot support heavy equipment or commercial trucks.

‍

Its position makes it a critical link for both local commuters and regional industry.

‍

Challenges

A severe flood destroyed the original bridge, forcing residents onto long, unsafe detours and cutting off access for agricultural machinery and freight transport.

‍

Early replacement concepts required a temporary bridge in 2024 and a permanent one in 2025, costing an estimated $5 million and extending disruption for years. The county needed a faster, more resilient, and more affordable solution.

‍

How we helped

The InQuik® System provided a permanent, disaster‑resilient integral bridge that could be installed quickly using prefabricated abutments, wingwalls, and lightweight deck panels.

‍

The collaborative CM/GC process bringing together the county, engineers, contractors, C‑DOT, and CMC, which enabled a streamlined build completed in under six months. With only 300 man‑hours required and a total cost of $2 million, the project restored safe access, strengthened flood resilience, and saved the county $3 million.
