SR 60 Peace River Bridge Replacements – Design Build Twin Bridges Low Level

Completed in 2002 by Johnson Bros. Corporation, the SR 60 Peace River Bridge Replacements – Design Build Twin Bridges Low Level project consisted of the Design-Build construction of major roadway and low-level bridge through environmentally sensitive Cypress swamp. Scope of work included maintenance of traffic (MOT); erosion/sedimentation control; prestressed concrete piling; major falsework and trestle placement, Sub and Superstructure; embankment; barrier walls; retaining walls; bank stabilizations; approach slab and roadway; guardrail system; rip rap rubble; gabions; and drainage. A unique flared cantilever wingwall was utilized that eliminated two piles and reduced the quantity of piling and concrete at each of the 8 locations on the bridges. Demolition of the existing bridges was phased so the existing bridge was used as work platforms. This saved time on the schedule. This project was completed 90 days ahead of schedule.
