2C Road Improvement

Transportation

Keeping a citywide repaving promise.

In 2015, Colorado Springs voters approved the 2C sales tax to tackle a backlog of failing streets, and they renewed it in 2019 and again in 2024. Since the program began in 2016 it has repaved more than 1,900 lane miles, rebuilt roughly 400 miles of curb and gutter, and installed thousands of new and retrofitted pedestrian ramps across the city — one of the largest sustained paving efforts in Colorado, with about half of every dollar going to the concrete beside the road.

Vivid Engineering serves as one of the lead quality assurance testing firms for the program’s concrete and asphalt work. Our technicians test and document paving, sidewalks, curbs, gutters, and pedestrian ramps across each year’s project list, verifying that every placement meets City specifications. That oversight protects the long-term durability of the investment and helps the City deliver smoother streets and better accessibility, year after year.

    Central 70 Project

    I-70, Brighton Boulevard to Chambers Road, Denver, CO

    Central 70 was the largest project in CDOT's history: a $1.2 billion reconstruction of 10 miles of Interstate 70 between Brighton Boulevard and Chambers Road, a corridor that carries more than 200,000 vehicles a day and supports some 1,200 businesses. The project added a new express lane in each direction, removed a 56-year-old viaduct, lowered the interstate between Brighton and Colorado Boulevards, and built a four-acre park over the highway to reconnect the Elyria-Swansea neighborhood to the rest of the city.<br /> <br /> Working alongside Kiewit Infrastructure Co., Vivid Engineering provided process control and field and laboratory materials testing for the project. Our technicians tested soils, concrete, asphalt, masonry, shotcrete, and aggregates throughout construction, verifying that every material placed met CDOT's quality standards on one of the most complex urban highway builds in the country.

    I-70 Floyd Hill to Chief Hosa Resurfacing

    I-70, Chief Hosa to Floyd Hill (MP 246.5 to 252.9), Jefferson and Clear Creek counties, CO

    Between Floyd Hill and Chief Hosa, I-70 climbs through the Front Range foothills carrying ski traffic, freight, and daily commuters in and out of the mountains — and its pavement had reached the end of its life. CDOT's $12.8 million resurfacing project rehabilitated 6.4 miles of the interstate (MP 246.5–252.9) through Jefferson and Clear Creek Counties, milling off deteriorated pavement and repaving both directions in stone matrix asphalt (SMA) — the durable, rut-resistant surfacing CDOT reserves for its hardest-working corridors. With no practical detour around this stretch of the mountains, contractor APC Construction completed all paving in a single season, almost entirely under nighttime lane closures, then returned the following season for guardrail replacement, culvert cleaning, signage, and striping.<br /> <br /> Working directly for CDOT, Vivid Engineering Group provided construction inspection, QA/QC administration, and field and laboratory owner acceptance materials testing across the project. SMA is one of the most demanding mixes to test — gap-graded, fiber-stabilized, and unforgiving on volumetrics — so Vivid ran the entire laboratory acceptance program from its on-site field lab, turning results while the mat was still going down. Vivid inspectors and certified technicians worked the night closures alongside the paving crews, verifying mix temperatures, compaction, and placement in real time; high-altitude paving windows, mountain weather, and live interstate traffic made every shift count, and Vivid's team kept acceptance testing and documentation moving on the contractor's schedule so the corridor reopened to full capacity every morning.

    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.
