Bridge Design    

Location: Home > Bridge Design

EST’s Bridge Division has four separate design teams. The design teams have performed work for a variety of clients including City, County and State Governments and Agencies. Our design teams consist of 3 Professional Engineers and 4 Engineering Interns.

EST’s experience includes bridge replacement projects for counties throughout the state, designing of new bridges on state and federal highways and rehabilitation of existing bridge structures. EST has the ability to provide our clients with complete, comprehensive bridge design services beginning with the initial survey and concluding with construction management on the project.

EST was the first engineering firm chosen to sign a contract with ODOT on the statewide Load Posted Bridge Design project due to EST’s ability to provide all the necessary services under one roof in a timely, efficient manner. EST is thoroughly familiar with all Federal, State, City and local design standards and guidelines and will work closely with our clients to ensure a successful project completion.

  • Interstate 35 over Fifth Street and Main Street, Bridges A & B - Location: Moore (Cleveland County)

Customer/Client: ODOT
Project Number: IMY-35-2(242)118

Project Location: Moore (Cleveland County)
Estimated Cost: $9,522,070.88
Bid Price: $8,251,978.20
Letting Date: February 2001

Both structures were designed with clear roadways of 120 ft divided by a single median barrier. The bridges were designed to have three 32 ft – 71 ft - 32 ft spans and an 18.5o skew to accommodate the orientations of Fifth Street and Main Street. Superstructure, abutments, and piers were designed to be constructed in three phases. The three-phase construction sequence allowed for three lanes of interstate traffic in both directions to be maintained simultaneously over Fifth Street and Main Street throughout construction. Only temporary closures of Fifth Street and Main Street were allowed. Pier caps were designed to accommodate the three phase construct sequence. Final pier caps were designed to be supported on existing columns and on new columns in the median. Temporary false work and jacking was designed to support dead and live loads carried by the existing pier caps between phases and before pier cap removals. The superstructures were also designed in three phases with supporting components consisting of the existing steel beams and new steel beams. All design was prepared in accordance with the AASHTO Standard Specifications for Highway Bridges.
