Mosser Lucas County Bridge

ODOT: Lucas County USR 24 – Fort to Port Highway

Lucas County, Ohio

The Ohio Department of Transportation awarded the joint venture team of Mosser Construction, Inc. and Beaver Excavating the $64 Million contract to construct the easternmost portion of the new 4-lane US 24 Fort to Port Highway.

With a compressed schedule, tight work area, and working heights in excess of 30’ h, incorporating the safety plan into the planning phase was paramount.  Walkways, handrail systems, access tie-off points were pre-planned to ensure worker safety and increase productivity.

Another key component of the project was the construction of two viaducts to carry traffic over a railroad and a two-lane connector ramp to link the new alignment with the existing highway.  Shoring design for the structure’s roof slab presented a major challenge for the team to accommodate the clearance requirements of the railroad. The support members also needed to span 20’-0” to maintain the permitted horizontal restriction of the railroad.

The two viaducts were created by two abutment walls and center pier wall that was capped with a 2’-8” roof slab.  To meet the spanning challenge, a 25’-6” w x 23’-11” h EFCO-designed Super Stud system was used; the other 32’-2” wide span employed a EFCO E-Z Deck shoring system.
