Keystone Chosen for Harrington Creek Bridge Water Line Relocation

STILLWATER, Okla. – The City of Stillwater has selected Keystone Engineering and Surveying as civil engineer for ODOT’s relocation of the Oklahoma Highway 51 bridge crossing Harrington Creek west of Stillwater.

Keystone will provide site surveys, construction design services, and support services throughout the bid and construction processes.

The project will entail the relocation of two parallel Rural Water Corporation #3 water lines within a private easement along the south side of the existing S.H. 51 right-of-way.

The two water lines will be replaced with one water line in a private easement outside the perpetual utility easements and rights-of-way, right of center. Directional drilling is the proposed method of construction, according to the Stillwater Water Utilities Department.

  • Verification of constructability with requested horizontal directional drilling method

  • Attendance to city council meetings, pre-bid conferences, and pre-construction conferences
  • Bid process management and documentation including minutes, addenda, and tabulation of results
  • Correspondence with the contractor during the construction phase as needed

All services will be performed in compliance with City of Stillwater, ODEQ, and ODOT standards. Upon completion of the Harrington Creek Bridge water line relocation, Keystone will provide the necessary final plans, drawings, and summary to the Stillwater City Council.
