Oliver Avenue over White River Bridge Rehabilitation 

Oliver Avenue over White River Bridge Rehabilitation Indianapolis, IN The Oliver Avenue over White River bridge was constructed in 1958 and has been designated as a “Select” historic bridge. DCCM completed the CE level 4 and provided all environmental and Section 106 services, including historic property report, historic bridge alternatives analysis, consulting party meeting and consultation, effect finding documentation, waters report, and NEPA documentation. DCCM expertly navigated the project through INDOT’s historic bridge project development process and worked with consulting parties, state agencies, and federal agencies to preserve the bridge while implementing meaningful repairs. DCCM detailed the arch patching and reconstruction of the brackets supporting the sidewalk and designed a fixed reinforced concrete deck with a protective membrane and underdrains to prevent future deterioration. DCCM also designed the rehabilitation details to bring the existing bridge railing, bridge sidewalks, and approach sidewalks into ADA compliance.

FM 2818 (Harvey Mitchell Parkway) Improvements

FM 2818 (Harvey Mitchell Parkway) Improvements College Station, Texas The FM 2818 (Harvey Mitchell Parkway) project in College Station showcases coordinated planning and innovative design to address regional growth and evolving transportation needs. DCCM led efforts with the City of College Station, TxDOT, Texas A&M University, and Easterwood Airport to improve corridor operations and support future expansion. DCCM’s scope included topographic surveying, ROW and easement identification, corridor and traffic analysis, conceptual alternatives analysis, environmental documentation, public involvement, subsurface utility engineering (SUE), and management of eight subconsultants. The team completed both schematic and PS&E phases, producing a geometric design from Wellborn Road to F&B Road and transitioning efficiently to construction documents by maintaining consistent staff and project management. A detailed topographic survey was completed for the 1.8‑mile corridor, covering an unusually large 80‑acre ROW. Prior baseline data from the 1970s and earlier DCCM utility surveys ensured accurate property and easement mapping. A comprehensive corridor and traffic analysis showed conventional intersections would not meet long‑term capacity needs. DCCM evaluated additional conceptual alternatives and identified a “superstreet” (Restricted Crossing U‑turn) as the preferred solution, reducing signal phases, improving traffic flow, and preserving flexibility for future controlled‑access upgrades. Environmental constraints along White Creek required careful grading and barrier design to minimize impacts on wetlands and floodplains. DCCM kept impacts below permitting thresholds and avoided additional ROW acquisition. DCCM also performed extensive SUE Quality Level (QL) B investigations covering more than 265,000 linear feet of utilities, revealing critical conflicts. Twenty-four QL-A test holes confirmed existing conditions and guided necessary design refinements. At the same time, additional QL-B work on side streets ensured a complete understanding of utility impacts despite tight timelines and traffic-control constraints. The project faced several significant design challenges, including a major underground electric duct bank that conflicted with proposed roadway and drainage improvements. Through SUE QL-A investigations and coordination with the City of College Station and TxDOT, the team adjusted the drainage while leaving the duct bank in place, thereby avoiding costly relocations. The late addition of the Jones‑Butler Road overpass required rapid schedule and design modifications without affecting the letting date.

West Terre Haute Trail

West Terre Haute Trail West Terre Haute, IN This one-mile-long pedestrian trail is located along the south side of US 150 in West Terre Haute, beginning at Sumner Avenue and extending east to Schley Place. The goal of this project was to improve pedestrian safety, increase connectivity, reduce congestion, and improve air quality.  Prior to construction, pedestrians were forced to walk along the narrow US 150 shoulder beside traffic or behind the guardrail adjacent to the steep side slope, creating a dangerous and restricted walking path. With this project, West Terre Haute was able to provide an alternate route for commuting individuals, families, and those needing to access jobs without vehicles. This trail and bridge improved safety for pedestrians and vehicular travelers amidst increased US 150 traffic.  At a Glance 1 Mile Project Size $6.6M Project Cost ACEC State Finalist Project Award Markets Transportation Environmental Services Transportation Environmental Structural Engineering
