Overley-Worman Park Pedestrian Bridge Zionsville, Indiana The Overley-Worman Park Pedestrian Bridge is located in a new re-purposed 53-acre park bounded by Eagle Creek, the Big-4 Rail Trail, the Vonterra Development, and I-865. The park features multi-use trails, a playground, picnic shelters, restrooms, woodland and creek overlooks, a fishing pond, mountain bike trails, and a disc golf course. Visitors can enter the park from the north Big-4 Rail Trail by crossing the new pedestrian bridge and onto one of Overley-Worman Park’s multi-use paths. The structure is a 200-ft. long single-span truss bridge with a 10-ft. width, supported by helical pile abutments. The bridge’s design blends into the park’s aesthetic by using a natural color scheme and a decorative faux stone veneer installed on the abutments. Completed 2022 Award ACEC State Finalist

Nowland Avenue Bridge Indianapolis, Indiana RQAW | DCCM provided bridge design, environmental, and historic architectural services for the Nowland Avenue Bridge over Pogue’s Run rehabilitation. Built in 1903, Nowland Avenue Bridge is one of Daniel B. Luten’s oldest structures in Indianapolis; however, the bridge was closed to all traffic due to decades of use and safety concerns. To restore the bridge, RQAW | DCCM provided design for superstructure and arch repair, roadway surface replacement, spandrel wall replacement, stabilization of the structure’s bank, drainage systems improvements, and updating railing and trail to meet ADA and AASHTO standards. Our team worked alongside the Indiana SHPO throughout the design process and coordinated heavily with the Pathways over Pogue’s group to provide a safe pedestrian crossing while conserving the structure’s significant historical elements. Completed 2023 Award ACEC Merit Award

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.

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.

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

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.
