KS Associates served as the prime consultant for this major corridor improvement project, under contract with the Ohio Department of Transportation District 3. The project extended north from the Ohio Turnpike to the I-90 interchange in the City of Elyria. This heavily traveled route experienced a high incidence of accidents. Travelers were confounded by the traffic pattern in this area, which required drivers to cross SR-57 via the 49th Street Bridge.
The purpose of the project was to more safely and efficiently move traffic, to improve connectivity for residents and businesses, and to accommodate future needs of the corridor.
In July 2009, KS Associates completed a Preliminary Engineering Study. The study provided ODOT with a cost estimate, conceptual plans, maintenance of traffic plans, a geotechnical investigation, and environmental studies for the preferred alternative. Recommended improvements included widening SR-57 to three lanes in each direction; constructing two at-grade, signalized intersections at Midway Boulevard and Griswold Road; removing the 49th Street Bridge; and removing loop ramps at I-90 and providing a full-diamond interchange.
KS managed five subconsultants for environmental and wetland services, lighting and drainage design, R/W acquisition, subsurface utility engineering, and geotechnical services.
The project broke ground on July 1, 2014, and was completed in 2016. KS also provided consulting services during construction.
