Summary
After reworking plans to use asphalt milling rather than full concrete replacement, the City Council awarded a contract for the west‑side improvements on East 90th Street North to Grama Line Construction for $6,869,000, funded from the Vision Recapture Fund and remaining general fund project surplus.
The Owasso City Council approved a contract award to Grama Line Construction for the west‑side roadway improvements on East 90th Street North, with the low bid reported at $6,869,000.
Public works staff explained the project scope includes reconstruction and widening of East 90th Street North from North 119th East Avenue to North 120th East Avenue (the transcript references the corridor using city street naming conventions). Dwayne Henderson said the city previously rejected bids for the combined bridge and roadway work in January 2024 because estimates exceeded budget; staff split the original project and completed the east side first. For the west side, engineers revised plans to mill and rework existing asphalt rather than replace full depth concrete after concrete estimates exceeded budget.
Henderson said the project will widen the outside lanes to the north and south, add right‑turn lanes and extend on‑ and off‑ramp lanes to allow two cars to queue for US‑169 ramps, and widen North 120th East Avenue approaches in advance of an anticipated bridge project in 2027. He told council the engineer's estimate was about $7.244 million; Grama Line Construction submitted the low bid at $6.869 million and other bidders were close behind. Henderson said funding is available through the Vision Recapture Fund and surplus general‑fund balance from a prior 116th Street North project.
Councilors asked why staff changed the design to asphalt milling; Henderson said rising concrete costs made full replacement cost‑prohibitive and milling the surface with asphalt overlay would reduce removal and material costs while producing an appearance similar to the original plan (black asphalt versus white concrete). He said typical asphalt surfacing life is 15–20 years compared with up to 40 years for concrete, but asphalt is easier and less costly to rehabilitate.
No members of the public spoke on the bid; the council approved the motion to award the contract on a roll call vote. Staff will proceed with contract execution and construction scheduling.
