Roadway

I-65 Added Travel Lanes Design-Build INDOT Crawfordsville District I-65 Design-Build project spanned from SR 38 to SR 25, with a gross length of 8.08 miles. RQAW | DCCM provided survey, environmental, design, and mitigation services. The design included 7.8 miles of roadway reconstruction with added travel lanes in the median through three Lafayette-area interchanges. There were 14 structures completed with assorted treatments: preservation, deck overlays, deck replacements, and widening. The design included four noise barriers, ITS Weigh-In-Motion replacement, pavement markings, signing, and maintenance-of-traffic plans including median barrier walls. RQAW | DCCM served as INDOT’s representative throughout the life of the project. RQAW developed the scope of work and prepared the bid package for the design/build letting, which included 30% plans, special provisions, and cost estimate. After the letting, RQAW | DCCM assisted INDOT in the review and evaluation of the technical proposal packages submitted by the contractor/ designer teams, provided review and approval recommendations of the final plan submittals and shop drawings by the design/builder team, and partnered with the consultant inspector on the project to provide technical support on an as-needed basis.  

Main Street & 4th Avenue Roundabout Carmel, Indiana This roundabout is located near a public library, school, and archway leading into the Carmel Arts & Design District; therefore, the geometry needed to be as small as possible to eliminate impacts to these areas while still allowing for school buses and emergency vehicles to make all necessary movements. Through our design, we were able to ensure that all turning movements and sight distance needs were met while minimizing the required right-of-way for construction. 

Redbird State Recreation Area Access Roadway INDOT Vincennes District This access roadway reconstruction project is within the Greene-Sullivan State Forest and the Redbird State Recreation Area. The project consisted of 7-ft to 11-ft wide travel lanes with 2-ft wide paved and 3-ft wide useable shoulders, resurfacing one county bridge deck, installing new guardrail, and replacing four existing small structures and several small drainage pipes. Four palustrine emergent and three palustrine forested wetlands were identified and delineated as well as 10 jurisdictional streams. RQAW | DCCM completed the State EA document and worked closely with the designers to remove several planned roadside ditches to avoid/minimize impacts to wetlands throughout the project.

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 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. 

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.
