The Bond issue calls for widening Washington from Garnett Road to Olive Avenue (129th Est Avenue) including all appurtenances. The improvements on Washington Street from Garnett Road to Olive Avenue include approximately 1.0 mile of roadway widening from 3 to 5 lanes with asphalt pavement along with the addition of concrete curb and gutter, sidewalk, trail, driveways, water line relocation, traffic signalization, enclosed storm sewer system, retaining wall, RCB bridge widening and RCP cross drain extension.
This construction contract consists of the reinforced concrete items from the ST1616 contract. This work includes the following items: reinforced concrete box culvert extension with wing walls, CET end treatments for a three span 72-inch reinforced concrete pipe, five end sections for a 10’ x 3’ reinforced concrete box, 440 linear foot retaining wall with a stem wall on each end, 213 linear foot parapet wall with moment slab, associated ornamental fences, and an add alternates for 5,125 linear foot multi-use trail and adjacent 1 ½ inch high density polyethylene pipe.

This Change Order #1 addresses the following additions to the contract:
- As directed by the City of Broken Arrow forces, the contractor is to fine grade the sloped embankments surrounding the south side outfall at the 72” RCP at STA 214+80. Upon completion of the fine grading the contractor shall install varying sizes of rock rip rap within the outfall constituting approximately 2350 Square Feet of floodway. The Rip Rap will also be grouted with CLSM to provide structure and prevent erosion.
- As directed by the City of Broken Arrow forces, the contractor shall remove, disposal, and reinstall “like kind” 6 foot perimeter fencing along the alignment between 224+00 & 228+50. This replacement of cedar perimeter fencing is due to conflicts with the installation of the new 10’ wide trail and drainage flume. The field measured length of perimeter fencing is 594 linear feet.
