SH 183 FRP Repairs
SH-183 girder rehabilitation connected formed concrete repairs and curing with targeted FRP application under coordinated roadway access.
Delta Structural Technology completed FRP repair work associated with SH-183 at Loop 12. The scope combined concrete girder restoration with composite reinforcement at a selected member. The proposed sequence addressed removal, anchoring, formwork, placement, curing and FRP application, while roadway closure was coordinated through the general contractor.

Project challenge
The repair package distinguished between girders requiring concrete restoration and the girder that also required FRP. Localized formed repairs and smaller hand-patched areas were included in the work concept. The team also reviewed an additional bridge location with a similar reinforcing need. Keeping those scopes distinct was important when establishing access, material quantities and the field sequence.
Project approach
Delta’s proposed procedure began with sawcutting repair edges and removing loose concrete. The sequence then included Hilti anchors, forms, bonding agent and placement of repair material, with wet burlap for curing. After form removal, FRP was to be applied to the identified girder, followed by painting. This linked the permanent composite work with the condition and cure of the restored concrete below it.
Delivery and coordination
The planning correspondence identified two lifts for access and assigned road closure to Southgate. Delta’s operations team reviewed the worksheet and the construction sequence before the scope was released. The review also considered the difference between a multi-girder concrete repair package and an additional single-girder scope, helping the team avoid treating them as identical construction efforts.
Project significance
SH-183 illustrates the relationship between formed concrete repair and a subsequent composite upgrade. FRP was one part of a multi-step girder treatment, with anchoring, curing and access included in the plan. The case demonstrates how a bridge repair can be organized around distinct member needs while maintaining a clear interface for roadway traffic control.
