Challenge: The City wanted a bypass around Seymour to allow for future development on the south side of the City, reduce truck traffic through downtown, and to provide additional options for emergency vehicles when trains are present.
Solution: This INDOT-LPA project with the City of Seymour involved constructing a new bypass around Seymour that is approximately 2.3 miles long. Awarded in November of 2019 and opened to traffic in November of 2021, this $17.3M project begins at the O’Brien Street intersection and extends to the northeast to connect at US 50/Burkart Boulevard. RQAW designed a 1.4-mile segment of new, two-lane HMA pavement roadway, including a 12-ft Shared-Use pedestrian trail along the north side, a single-lane roundabout at the O’Brien St intersection, and approximately 3,800-ft of MSE retaining wall. The existing railroad bridge was approximately 90-ft in length to cross over the L&I Railroad and required extensive railroad coordination. Additionally, due to a new alignment, RQAW also designed a new stormwater system including storm sewers, ditches, small structures, and detention (dry) ponds for 29 ac. of developed area to meet the city’s stormwater requirement for development. The detention ponds were designed to provide storage for additional discharge created by the impervious areas of the new road pavement. For this new roadway phase, RQAW also provided Construction Inspection Services and was pivotal in providing Environmental Services for the required permits and approval of environmental documents.
