According to the study, 5,928 of Oklahoma’s 23,528 highway
and local bridges had been deemed structurally deficient in 2007, which ranked
second highest of all states. By 2016, that number had been reduced to 3,460 deficient
bridges, meaning there were 2,468 fewer deficient bridges in 2016 than there
were in 2007, accounting for a 41.6 percent reduction in deficient bridges, the
largest reduction in the country.
Garver came to Oklahoma in 1993 and has offices in Tulsa and Norman, and is a longtime consultant with ODOT. The company's Transportation Team aided in the reduction of deficient bridges by leading several projects that have provided Oklahoma with new highway bridges.
“Garver and ODOT have had a great working
relationship over the years,” said
Garver Bridge Team Leader Jason Langhammer. “We’re thrilled to see it making
such great progress on these projects that are so important to the daily lives of all Oklahomans, and we’re proud that we’ve played at least a small part in that.”
Examples of Garver’s contributions to ODOT's reduction of deficient
bridges include:
Load-posted bridge replacement program
Garver provided design plans for six projects included in ODOT’s load-posted bridge replacement
program. The work included survey, grading, drainage, and roadway design, traffic
control, hydraulic analysis, geotechnical investigation, and design to replace
bridges on offset and existing alignments. The project included replacing highway
bridges in three different counties over Big Cedar, Spencer, Gaines, Dry and Mud,
Walnut, and Albion Creeks.
Various bridge replacement projects, Ottawa County, Oklahoma

Garver contracted with ODOT to reconstruct three bridges in Ottawa County. The scope included the reconstruction of a rural two-lane highway and bridge over Sycamore Creek, to produce a conceptual design study for the interchange and bridge at the U.S. 60/U.S. 59 interchange, and to replace the U.S. 69 bridge over Tar Creek in Ottawa County. Design services included survey, bridge hydraulic analysis, roadway and traffic design, and bridge design. In replacing State Highway 10 over Sycamore Creek, Garver provided bridge hydraulic analysis, roadway and traffic design, and bridge design, while upgrading the bridge to 12-foot lanes and eight-foot shoulders. Garver also provided a preliminary engineering study, roadway, traffic, and bridge design for the U.S. 60 bridge over U.S. 59.
Various bridge replacement projects, Grant County, Oklahoma

Garver provided a preliminary engineering and final design services for three bridge replacement projects in Grant County. U.S. 60 over Pond Creek was replaced with a curved four-span, prestressed beam structure, U.S. 81 over Polecat Creek and one unnamed creek was replaced with a three-span beam bridge, and U.S. Highway 60 bridge over Boggy Creek was widened for 12-foot driving lanes with eight-foot paved shoulders.
Interstate 44 interchange at 165th East Avenue, Phase 1, Tulsa, Oklahoma

Garver provided design services for one mile of Interstate
44 over N 165th East Avenue in Tulsa, which included grading,
drainage, surfacing, erosion control, traffic control, bridge widening, traffic
signal warrants, level of service analysis, highway signage, and pavement
markings. Garver also worked with ODOT to determine future roadway capacity requirements for 165th East Avenue and surrounding
roadways.
State Highway 51 over Cottonwood Creek, Creek County, Oklahoma

Garver provided design services for ODOT's first accelerated bridge construction (ABC) project that was
required to match the existing bridge and roadway alignments. Two bridge alternates
were designed for final plans, after which a transverse, sliding/skidding
bridge move was selected to replace the existing bridge on the existing alignment
after it was constructed on temporary supports adjacent to the existing
structure. A track system was used to move the bridge into position atop new piers and abutments, allowing the existing bridge to stay in service while the new bridge was being constructed.
I-244 multimodal bridge over the Arkansas River, Tulsa, Oklahoma

Garver assisted ODOT in preparing conceptual design data for inclusion in a Transportation Investment Generating Economic Recovery (TIGER) grant application. After selection, Garver prepared a preliminary engineering report, preliminary engineering plans, and final plans, specifications, and estimates within an accelerated nine-month schedule. And while not structurally deficient, the project replaced what had been a structurally deteriorating bridge. The completed I-244 westbound multimodal bridge that spans the Arkansas River in Tulsa, includes four lanes of highway traffic on one level, and one High Speed Rail Line and pedestrian traffic on another level. The eastbound bridge is currently under construction.
