I-25/Cimarron Interchange Design Build

Transportation

Rebuilding the gateway to downtown Colorado Springs.

The I-25/Cimarron Street (US 24) interchange is the gateway to downtown Colorado Springs and one of the busiest junctions in the Pikes Peak region. Decades of poor roadway performance — settlement of embankments and walls on soft soils along Fountain Creek — had made it a persistent maintenance problem. CDOT’s $77 million design-build reconstruction, delivered with Kraemer North America, completely rebuilt the interchange: new bridge foundations and bridges, new embankments, numerous MSE retaining walls, temporary and permanent pavements, improvements to the major drainages, and culvert and jack-and-bore utility installations.

Vivid Engineering supported the project with quality oversight, construction inspection and materials testing, geotechnical design, and structural fill monitoring. Because of the corridor’s history of settlement, significant analysis, design, and construction monitoring were performed to protect the new embankments and retaining walls — work grounded in our team’s deep experience with DOT and FHWA design-build requirements, procedures, and specifications. The result is a modern interchange built to perform on ground that had troubled the corridor for decades.

    Cañon City's 2A Street Repair

    1st Street and Main Street, Cañon City, CO 81212

    In November 2016, Cañon City voters approved Referendum 2A, a one-percent sales tax dedicated entirely to repairing and replacing the city's streets. The 2024 program year was one of the largest to date: a $6.55 million slate that included full reconstruction of 1st and Main Street from US 50 to 4th Street and Pear Avenue from 19th Street to Field Avenue, along with resurfacing of 5th Street between Fairview Avenue and High Street and Harrison Avenue between 9th and 15th Streets. Year by year, the 2A program has worked through the roughly two-thirds of city streets once rated in poor condition.<br /> <br /> Vivid Engineering served as project manager and the inspection and testing lead for the 2024 work — managing construction on the City's behalf, inspecting reconstruction and paving operations, and testing soils, aggregates, concrete, and asphalt against project specifications. The result is a set of rebuilt downtown streets that meet national standards and will serve Cañon City for decades.

    City of Cañon City Referendum 2A Program

    Citywide street program, Cañon City, CO 81212

    In November 2016, Cañon City voters approved Referendum 2A, a one-percent sales tax increase dedicated exclusively to contracting out street repair and replacement. The tax generates an average of $3.5 million a year across a 10-year program — $9 million of design-build work in the first year, 2017, followed by annual design-bid-build programs every year since.<br /> <br /> Vivid serves as the City's prime consultant and owner's representative for the program. Our team performs geotechnical investigations; prepares pavement designs for composite pavement, full-depth reclamation, and asphalt and concrete mill-and-overlay; and delivers civil plans and specifications covering roadway plan and profile, utility relocations, drainage, streetscape and ADA compliance, Safe Routes to School, stormwater management, quantities, and engineer's estimates, with Wilson & Company preparing civil plans as a subconsultant. Vivid supports bid document preparation, bid award, and pre-construction meetings, then serves as construction engineer through the build — providing construction inspection, quality management, and materials testing on every project. The result is a program that has steadily rebuilt the streets Cañon City residents voted to fix.

    Downtown Estes Loop Project

    Elkhorn Avenue, Moraine Avenue, and Riverside Drive, Estes Park, CO 80517

    Every year, millions of visitors funnel through downtown Estes Park on their way to Rocky Mountain National Park — and for decades, its two-way downtown streets could not keep up. The $42 million Downtown Estes Loop, administered by FHWA's Central Federal Lands Highway Division in partnership with CDOT and the Town of Estes Park, converted Elkhorn Avenue (US 36), Moraine Avenue, and Riverside Drive into a one-way couplet. The project built a new roundabout at Moraine and West Riverside, replaced the bridge over the Big Thompson River connecting East and West Riverside Drives, and delivered expanded stormwater infrastructure, floodplain mitigation, and new sidewalks and trails through the heart of downtown.<br /> <br /> Working for Flatiron, Vivid Engineering Group provided construction inspection plus field and laboratory materials testing of soils, aggregates, concrete, and asphalt across 21 months of construction, from January 2023 to October 2024. Building a federal-aid project through an operating tourist downtown meant compressed winter work windows and some of the toughest environmental restrictions on any Colorado project — with the Big Thompson River flowing directly through the work zone. Vivid's inspectors and technicians kept quality verification moving on the contractor's schedule, with samples run through our AASHTO-accredited Colorado laboratories, so that the Loop opened to traffic ahead of the next summer season.
