US 36 Added Travel Lanes Phase 1

/

US 36 Added Travel Lanes Phase 1 Avon, Indiana | InDOT Crawsfordville District Paving the way for a growing community Challenge: The recent growth of Avon significantly influenced the initiation of the project, as it led to heightened safety concerns and increased traffic in this very commercialized area. Solution: US 36 from Shiloh Park Drive to Raceway Road was the first phase of a large-scale corridor improvement plan. RQAW | DCCM obtained traffic counts, developed a corridor model, and created an analysis to guide and refine the limits of this added travel lanes project. Through our findings, our team addressed the excessive traffic volumes by recommending an additional third travel lane in eastbound and westbound directions by proposing converting existing shoulders into travel lanes, turning the existing two-way left turn lane (TWLTL) into a curbed center median, and improving impacted intersections. Our approach resulted in no public controversy while minimizing construction costs, high crash rates, and the need for land acquisition.

SR 39 ADA Curb Ramps & Sidewalks

SR 39 ADA Curb Ramps & Sidewalks INDOT Crawfordsville District RQAW | DCCM was chosen to upgrade 32 curb ramps along SR 39 from Reagan Street to the north limit in the Town of Clayton. This project’s goal was to make all ramps ADA compliant; however, our team was able to utilize several innovative solutions throughout the design process. These solutions included inspecting existing ramps to determine if any grades and slopes were up to INDOT standards. Ramps that were found to be acceptable were maintained and any sites that were near satisfactory were retrofit with a detectable warning surface, rather than fully replaced. This process ultimately reduced the project cost by over 50%.

SR 234 HMA Overlay

SR 234 HMA Overlay INDOT Crawfordsville District This partial 3R, minor structural overlay project located in Montgomery County was 11 miles in length and extended through the Town of Ladoga. The cross-section of the roadway remained unchanged, except at locations where two-ft shoulders were added within the existing right-of-way. The existing cross slope was corrected to two percent outside the town. Within Ladoga, the existing cross slope was perpetuated, and a Level 1 design exception was obtained. In addition, 19 curb ramps within Ladoga were replaced due to ADA deficiencies. New truncated domes were installed on four additional curb ramps. RQAW | DCCM coordinated extensively with the INDOT ADA Committee to minimize the impacts to the downtown area.

Arlington Avenue & Shelbyville Road Roundabout

Arlington Avenue & Shelbyville Road Roundabout Indianapolis Department of Public Works This functionally obsolete intersection of Arlington Avenue and Shelbyville Road was originally a four-way, stop-controlled intersection with an approach that consisted of two 10-ft travel lanes in each direction. To accommodate the increasing amount of traffic in the area, RQAW | DCCM realigned Arlington Avenue to integrate a turning movement so that traffic, including semis, could navigate the roundabout properly. The final design was a small geometrical, single-lane roundabout with an inscribed circle diameter of 100 ft in a way that minimally impacted surrounding right-of-way and utilities. 

Knox County Wide Bridge Inspection

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

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

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

/

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

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

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.
