I-70 Floyd Hill Project

Transportation

Construction inspection on CDOT's $905 million rebuild of eight miles of I-70 from Floyd Hill to the Veterans Memorial Tunnels.

  • $905MCorridor Investment
  • 8 MIOf I-70 Rebuilt
  • 3 NEWInterchange Roundabouts

Rebuilding the mountain corridor's toughest eight miles.

Where I-70 drops off Floyd Hill and threads Clear Creek Canyon to the Veterans Memorial Tunnels, the interstate narrows, curves, and climbs some of the steepest grades on the mountain corridor – a bottleneck for ski traffic, freight, and every trip between Denver and the high country. CDOT’s $905 million I-70 Floyd Hill Project is rebuilding eight miles of the corridor (MP 241-248) through Clear Creek County: adding a third westbound lane that will operate as a tolled Express Lane, realigning the highway for better sight distance, replacing worn bridges – including an elevated section carrying westbound traffic through the canyon – building a two-mile frontage road between the US 6 and Hidden Valley interchanges, adding roundabouts at three interchange locations, and improving the Clear Creek Greenway below. Design-build contractor Kraemer North America broke ground in 2023, with westbound traffic slated for its new alignment in 2027 and full completion in 2029.

Working directly for CDOT, Vivid Engineering Group provides construction inspection on the project – verifying that the work going in the ground matches the plans and specifications on one of the most complex active corridors in the state. Vivid inspectors cover the full range of heavy-civil operations: drilled shafts and pier columns rising out of the canyon floor, girder erection and bridge deck placements, rock excavation and retaining walls, earthwork, paving, and drainage – all built under live interstate traffic in a narrow canyon shared with Clear Creek and the greenway. It’s exactly the kind of high-stakes, high-country work Vivid’s inspection team was built for.

    Military Access, Mobility & Safety Improvement Project

    South Academy Boulevard widening and Pikes Peak region corridors, El Paso County, CO

    The Military Access, Mobility & Safety Improvement Project (MAMSIP) is a $161 million, five-year program to improve the corridors connecting Fort Carson, Peterson Space Force Base, Schriever Space Force Base, and Cheyenne Mountain Space Force Station — funded by CDOT, El Paso County, the Pikes Peak Rural Transportation Authority, and an $18.35 million federal BUILD grant. Built by SEMA Construction from June 2021 to July 2026, the program delivered safety improvements and a jug-handle intersection on CO 94; a full rebuild of Charter Oak Ranch Road with a new roundabout at Santa Fe Avenue; 7.5 miles of I-25 work between South Academy Boulevard and Fountain, including two replacement bridges, a concrete overlay, and a full-length median barrier; and finally the widening of South Academy Boulevard from two to three lanes in each direction, with bridge widening over Fountain Creek, US 85/87, and Bradley Road.<br /> <br /> Vivid Engineering served as the lead materials quality assurance testing firm for the program, overseeing all materials documentation, field testing, and inspection — including the South Academy Boulevard widening in El Paso County — to verify that every element met CDOT and FHWA standards for safety and durability.

    Academy Boulevard Improvements

    South Academy Boulevard, Bijou Street to Airport Road, Colorado Springs, CO

    South Academy Boulevard is one of Colorado Springs' hardest-working arterials, and decades of heavy traffic had left its pavement, concrete, and drainage in poor condition. The City's $62.5 million South Academy Boulevard Improvements Project, funded through the voter-approved Pikes Peak Rural Transportation Authority, is rebuilding 18 lane miles in two segments — Bijou Street to Airport Road, and East Fountain Boulevard to Jet Wing Drive. The work replaces worn pavement and base, rebuilds curb and gutter, adds a multi-use path, relocates Colorado Springs Utilities water and wastewater lines, and installs new inlets, manholes, and storm pipe to end chronic standing water.<br /> <br /> Vivid Engineering leads quality assurance testing and is part of the inspection team for the project. Our technicians sample and test soils, aggregate base, concrete, and asphalt as each phase goes in, keeping results in the contractor's hands so work can keep moving through a corridor that stays open to traffic throughout construction. Segment 1 wrapped up in 2024, with the southern segment scheduled for completion in 2026.

    CO 119 Safety, Mobility & Bikeway Project

    CO 119 (Diagonal Highway), Foothills Parkway in Boulder to Hover Street in Longmont

    CO 119 — the Diagonal Highway — is Boulder County's busiest commuter corridor, linking Boulder and Longmont across 10 miles of open farmland and a growing string of intersections. CDOT's $165 million CO 119 Safety, Mobility & Bikeway Project, delivered in two construction packages with Kraemer North America and funded by CDOT, RTD, Boulder County, and a 2023 federal RAISE grant, is reshaping the corridor from Foothills Parkway to Hover Street. The project adds a separated commuter bikeway running the length of the highway, with four underpasses at CO 119, Niwot Road, CO 52, and Jay Road and an overpass at 63rd Street; new Bus Rapid Transit infrastructure and Park-n-Ride facilities; a reconfigured CO 52 intersection; and safety improvements at intersections along the route. Construction began in September 2024, with completion expected in spring 2027 — all while the highway stays open to the tens of thousands of commuters who depend on it every day.<br /> <br /> Vivid Engineering Group provides field and laboratory materials testing across both construction packages, working alongside Kraemer and CDOT Region 4. Our technicians sample and test soils, aggregate base course, concrete paving (PCCP), structural concrete for bridge decks, caissons, and drainage structures, and asphalt, performing CDOT owner acceptance sampling and testing to verify that every material placed meets specification, with samples run through Vivid's AASHTO-accredited Colorado laboratories. On site since 2024, the team has supported early-morning fast-track paving pours, bridge deck placements, caisson pours, and embankment work — keeping acceptance testing and documentation moving at the pace of one of the fastest-moving corridor projects in the state.
