Knox County Wide Bridge Inspection Lawrence, Indiana RQAW | DCCM has been responsible for multiple 4-year cycles to inspect the 196 bridges owned by Knox County. This inventory of bridges includes 26 fracture critical structures, 1 structure requiring an underwater inspection, and 8 bridges on the annual inspection cycle. Our inspection teams verify the structural condition of each bridge and notify the highway department of any identified safety issues.
Old City Park Pedestrian Bridge RQAW | DCCM engineers analyzed the bridge loads and park’s topographic features to design the abutments. These abutments were supported on a concrete spread footing and contained concrete wingwalls. Our designers developed a geometric layout to minimize flooding at the bridge site, including incorporating IDNR ‘construction in floodway’ requirements. Our team incorporated architectural features into the concrete abutments to blend the custom pedestrian bridge seamlessly into the park overall aesthetic.
Pagoda Drive Over Pleasant Run Indianapolis, Indiana Preserving historic look, integrating modern safety measures Challenge: Prior to construction, the structure was experiencing deterioration and received an overall critical structural rating, making it dangerous for the traveling public. The bridge also needed updates due to heavy, daily traffic flow in and out of Garfield Park. Solution: The team was able to replicate the bridge’s memorable arch shape and historic characteristics by developing a cast-in-place structure. All historical features were designed to match the look of the existing structure and incorporated salvaged stone material from the original remnant dam walls. Our engineers incorporated aspects of the existing barrier wall into the new custom barrier designed to meet ADA requirements to provide safe access for pedestrians into the park.

Old Meridian Street & Carmel Drive Roundabout This project replaced a signal-controlled intersection and protected left-hand turning lanes with a 2-lane roundabout. The design avoided a $1.0M relocation on the northeast corner of the project. The intersection improvement upgraded the level of service, improved the overall safety of the intersection, and improved intersection control for the City of Carmel while increasing intersection capacity.
Oliver Avenue Over the White River Indianapolis, Indiana Bridging the gap between historic integrity and long-term serviceability Challenge: Prior to rehabilitation, the structure deteriorated to the point where it was rated as Structurally Deficient, which threatened the bridge’s long-term function as a vital connection in downtown Indianapolis. Solution: RQAW | DCCM took great care to preserve the integrity of the bridge by ensuring that construction work was completed without changing the appearance of the bridge or the overall concept of the nearly 100-year-old structure. While safety and structural improvements were completed to meet ADA standards, RQAW | DCCM was able to restore the structure’s full capacity to serve the community while preserving its notable and historic elements.

SR 234 Bridge Replacement INDOT Crawfordsville District RQAW | DCCM led the project development for the SR 234 over Little Raccoon Creek bridge replacement project. Located nearLadoga, the new bridge structure is a 32 feet by 10 feet threesided concrete box. Because of the project location’s 30-degree skew and a T-intersection, RQAW | DCCM designed the new box to be 68 feet long to span the SR 234 roadway section and provided a complex grading design to match the southwest wingwall into a new pipe that was installed under the county road. The roadway grade was also raised 9 inches to accommodate a minimum cover over the new box with vertical alignment developed to minimize pavement replacement needs. Though tree cutting was required for the project, the team worked to minimize impacts to the surrounding area and wildlife.
Sullivan County Bridge Inspection Our team of certified bridge inspectors performed on-site inspections of the County’s 175 structures, which included 7 fracture critical structures. These bridges were inspected in bi-annual cycles, with 10 of the bridges requiring additional inspections on an annual basis. Our team ensured the structures were in safe condition, and all safety features such as load posting signs, guardrails and deck railings were installed properly.
The Parklands of Jasper Jasper, Indiana Designing structural supports to complement the landscape Challenge: The client needed a structural engineer to compliment the architectural design for the bridge abutments. These needed to support a very large pedestrian bridge and maintain an aesthetic look that matched the rest of the park. Solution: RQAW | DCCM engineers analyzed the bridge loads and topographic features of the park to design the deep foundation abutments, wingwalls and geometric layout for the new pedestrian bridge nestled over two water cascades that flow into a natural pond and surrounding wetland area. Our designers incorporated aesthetic features into the concrete abutments to blend the large pedestrian bridge seamlessly into the park environment. RQAW | DCCM’s environmental team performed permitting, wetland delineation, coordination with the USACE and IDEM for stream/wetland impacts and mitigation, wetland mitigation design, completed a “waters of the US”/wetland delineation report and mitigation, and are providing an ongoing wetland mitigation monitoring. Cost $800,000 Award Environmental Stewardship Award Completed 2018
Fall Creek Trails Fishers, Indiana Fall Creek Woods Natural Area consists of an 80-acre property boasting amenities such as hiking and wildlife viewing. With over 3.2 miles of trails, this newly designed project is perfect for a scenic hike. RQAW | DCCM designed this project which consisted of a 40 and 80-foot pedestrian bridge over the wooded ravines, and a 600-foot switchback that connects the trails within the park. In total, more than 150 helical piers were bored into the ravine to hold the structure together. Award ACEC Sate Finalist Award Completed 2023 Size 1,500 Linear Feet
West Terre Haute Trail Terre Haute, Indiana Connecting the community, protecting the environment Challenge: Prior to construction, pedestrians were forced to walk along the busy and narrow US 150 shoulder alongside traffic or behind the guardrail adjacent to the steep side slope, creating a dangerous and restricted walking path. Due to the Wabashiki Fish and Wildlife Area, it was also crucial that all designs were suitable for nearby marsh bird species, endangered plants, pollinators, and turtles. Solution: RQAW | DCCM worked with the town to design an economical and sustainable one-mile-long trail and pedestrian bridge that promotes a safer alternative route for pedestrians traveling through the corridor while minimizing disruptions to the community, flora, and fauna. To protect the area’s wildlife, RQAW | DCCM’s environmental experts installed culverts under the road and trail and an exclusion fence to reduce the number of turtle-vehicle collisions while alternating construction to prevent disturbances to endangered species within the area.
