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 4-lane US 24 Fort to Port Highway.
With a compressed schedule, tight work area, and working heights in excess of 30’ h, incorporating safety into the planning phase was paramount. Walkways, handrail systems, and 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.
