Bridge Design: Kohli & Kaliher Associates offers bridge services including construction and rehabilitation plans for both public and private structures.  Our experience includes roadway, pedestrian and railroad bridges and underpasses.  We are prequalified with the Ohio State Department of Transportation for Level 1 and Level 2 Bridge Design.

DEF-24-7.96 This project improved three miles of U.S. 24 on the west side of Defiance, Ohio from an existing Super 2 highway into a 4-lane divided highway. Included in the project was the design of two twin river bridges, one twin overpass structure; the complete redesign and replacement of the U.S. 24 / S.R. 15-18 interchange; and the construction of a connector road and other intersecting roads. The following structures were designed by Kohli & Kaliher and are detailed on the following page as found by clicking on the DEF-24-7.96 title: U.S. 24 Bridges over the Tiffin River; U.S. 24 Bridges over West High Street; and the S.R. 15/18 Bridge over U.S. 24. The design plans for this $36.7 million project were completed in 2005 for ODOT District One.

LUC-280-1.64 This project involved the reconstruction of 0.53 miles of I-280 urban interstate in the City of Toledo including the reconstruction of a CSXT Railroad Bridge over I-280, a temporary railroad run-around structure over I-280, and a new I-280 bridge over Starr Avenue. The CSXT Railroad Bridge and the bridges over Starr Avenue were designed by Kohli & Kaliher and are detailed on the following page as found by clicking on the LUC-280-1.64 title. Construction of this $17 million project was completed in 2003 for ODOT District Two.

WIL-C.R. 19 (C.R. 10) This project involved the replacement of a single span (121’ clear span) steel truss bridge over the St. Joseph River with a new three span steel beam superstructure supported on semi-integral abutments supported on piles and capped pile piers. This river crossing is located at the intersection of C.R. 19 (C.R. 10) and C.R. 29 (Road K). The existing bridge was built at a diagonal connecting the four roadway legs. The proposed design made C.R. 19 into a through road, with C.R. 29 intersection at stop conditions. Category 3 wetlands were located within the project site, necessitating that all work be performed without disturbing them. As a result, the intersection radius of the east leg of C.R. 29 intersects C.R. 19 on the proposed bridge, resulting in a “Y-shaped” bridge. This resulted in a unique design that required extensive design calculations and plan detailing with regards to the steel beam design and the altered abutments and piers. A soldier-pile retaining wall was also constructed in one quadrant to avoid wetland impacts. Construction of this $1,230,000 project was opened to traffic in 2004, with finishing work completed in Spring 2005, for the Williams County Engineer

PUT-C.R. 3-10.40 This project involved the design of a new bridge over the Blanchard River on new alignment in the Village of Gilboa, Ohio. Approximately 2550 linear feet of roadway work was also required, both in the construction of the new roadway alignment and bridge approach embankment and necessary work on intersecting side roads both inside and outside of the village. The proposed structure was a four span (75’ c/c bearings each span), prestressed concrete box beam superstructure supported on reinforced concrete capped pile abutments and reinforced concrete wall abutments founded in bedrock. As part of the design, extensive consideration and analysis was placed on raising the profile of Main Street to eliminate regular flooding in the area. Construction inspection was also performed by Kohli & Kaliher and this $980,000 project was completed in 2003 for the Putnam County Engineer.
