History

US Highway 287 is an alternative to the increasingly congested Interstate 25 corridor for entering Loveland, and it provides access to the city’s many recreational amenities along the Big Thompson River corridor.

The Big Thompson River has sustained 13 damaging floods, the most recent in September 2013, resulting in significant damage to public infrastructure and private properties in Loveland. Of particular concern was the area of the Big Thompson near US 287 (Lincoln Avenue) with its vital north-south highway connection into the city, the Burlington Northern-Santa Fe Railroad tracks, two large community parks, the Loveland Fire Rescue Authority’s training facility and a dense cluster of buildings and businesses.

Excluding the cost for emergency response, the 2013 flood caused $9.9 million in damage to public infrastructure in this area. That’s over $18 million in today’s dollars. The US 287 bridge nearly failed from scour undermining the piers and north abutment, and the highway was closed for more than two weeks as the river overtopped the roadway. Many businesses were closed for months due to significant flood damage.

The need for more resiliency in this area following the 2013 flood led to the creation of the Big Thompson River Corridor Master Plan, which was adopted by City Council in June 2019. This plan identifies numerous projects and river maintenance activities to implement along the nine-mile stretch of the river through the Loveland area.

Along with these river corridor enhancements, the City of Loveland is improving the US 287 and State Highway (SH) 402 intersection and rebuilding the US 287 bridge over the Big Thompson River as part of the Highway 287 Flood Mitigation project.

Project Description

The Highway 287 Flood Mitigation project is a joint effort between the City of Loveland, the Colorado Department of Homeland Security and Emergency Management (DHSEM) the Federal Emergency Management Agency (FEMA) and the Colorado Department of Transportation (CDOT) to design flood mitigation measures for the Big Thompson River at Highway 287. This project will focus on the US 287 bridge, but the entire project area extends from Railroad Avenue on the west to about Saint Louis Avenue on the east. Along US 287, the project area extends about 1,000 feet to the north and south of the river.

The project has three main components: bridge replacement and retrofitting, stream restoration, and floodplain improvement. A primary goal is to increase community resiliency by removing as many properties as feasible from the 100-year floodplain and reducing flood risk to those structures that remain in the floodplain.

The US 287 and SH 402 Intersection Improvement project is a key component of the Highway 402 Corridor Plan that outlines the city’s plans for improvement, beautification and revitalization of the 4.2-mile SH 402 corridor from I-25 to S. Taft Avenue. This intersection improvement project will address traffic congestion, reduce safety concerns and support regional access. Its limits extend from the end of the US 287 bridge improvements to approximately 400 feet south of the intersection.

Project Scope

The Highway 287 Flood Mitigation project includes building a new US 287 bridge structure over the Big Thompson River. This new bridge will be about 4 feet higher than the existing structure and will include four through lanes, a center turn lane, bike lanes and a sidewalk. Other project elements include:

  • Addressing access points throughout the project corridor to accommodate raising the bridge and highway about 4 feet to help prevent the river from overtopping the roadway.
  • Creating a natural open space corridor by connecting the existing public natural areas and parks just upstream and downstream of the bridge.
  • Reducing flood risk by increasing floodplain capacity adjacent to the river channel and using nature-based solutions (things such as planted vegetation or boulders).
  • Improving opportunities for public interaction with the river through better access.
  • Restoring natural areas and improving river health as best as possible.
  • Creating a signature southern entrance into Loveland.

The US 287 and SH 402 Intersection Improvement project includes these elements:

  • Widening and reconfiguring the intersection approaches to address safety concerns and improve travel times with dedicated turning movements.
  • Partnering with adjacent stakeholders to provide right-of-way improvements and increase economic opportunity and redevelopment for SH 402.
  • Improving pedestrian crossings, curb ramps and sidewalks to enhance safety and accessibility.
  • See this conceptual exhibit of the project improvements.

Project Funding

The river corridor improvements, reconstruction of the US 287 bridge and improvements to the US 287 and SH 402 intersection will cost an estimated $50 million. To help cover the cost of these projects, the City of Loveland has submitted a BUILD grant application to the U.S. Department of Transportation. BUILD grant funds would also be used to improve the intersection of US 34 and US 287.

    Roy asked about 2 years ago

    Hello! Thank you for your comment. The Highway 287 Flood Mitigation Project is a comprehensive river corridor project that ties into the "A Better Big T" Master Plan. The master plan addresses the most critical issues by improving areas of the river along U.S. Highway 287 and determining the impacts of Loveland's floodplains. The Highway 287 Flood Mitigation Project will focus on on the Highway 287 bridge, but the entire project area extends from Railroad Avenue on the west to about Saint Louis Avenue on the east. Along Highway 287, the project area extends about 1,000 feet to the north and south of the river.

    This project has three main components: bridge replacement and retrofitting, stream restoration and floodplain improvement. A primary goal is to increase community resiliency by reducing flood risk to those structures that remain in the floodplain.

    You bring up some great points about other important transportation connections and future projects. In October 2023, Loveland's City Council adopted Connect Loveland, which addresses our transportation master plan for Loveland through 2040. The 402 Corridor will be widened per the transportation plan as the area develops.   

    We have shared your comment to our Transportation and Stormwater Engineering Divisions. If you have additional questions, you can contact us at 970-962-2524 or PublicWorksInfo@cityofloveland.org. Thank you!

    Will you be annexing the St Louis Bridge?

    Caryn asked about 2 years ago

    Hello! Thank you for your question. The St Louis Bridge is in the growth management area for the City of Loveland. As we look at future infrastructure and the City's transportation master plan, Connect Loveland, St Louis Bridge could be potentially annexed in the future. If you have questions specifically about our growth management plan, you can contact our Transportation or Stormwater Divisions at 970-962-2524 or PublicWorksInfo@cityofloveland.org. Thank you!

    jimboers asked about 2 years ago

    Hello, thank you for your question! Yes, the plan is to have a pedestrian underpass for the recreation trail under the new bridge, like the existing underpass for bikers and walkers along the Big Thompson River. We are working collaboratively with the Parks and Recreation Department. If you would like to discuss this more specifically with the Parks and Recreation engineers for this project, you can contact them at 970-962-2727 or parks@cityofloveland.org. Thank you!
