SR-543, I-5 to International Boundary Widening & Border Crossing Improvements

Project Summary

The SR 543 Project reconstructed the truck crossing lanes and the US-Canadian Border in Blaine, Washington. Work included construction of two bridges, cast-in-place concrete retaining walls, noise walls and new concrete roadways.  The project was granted substantial completion 176 working days ahead of the allowed contract time.  

On this project, our team used the "Partnering Method” with the owner, which contributed to the success of the project, and as a result both WSDOT and IMCO make an effort to implement Partnering on all projects.  Also on this project, IMCO established a great working relationship with Canadian and United States Border officials and was able to perform the work effectively and timely to all parties’ satisfaction. Our crews installed concrete drilled shafts during the winter; which posed a huge erosion and sediment control concern. In working closely with WSDOT and DOE, IMCO maintained permit compliance.

A Cost Reduction Incentive Proposal (CRIP) was submitted by IMCO, eliminating a detour phase of the project.  This turned out to be a huge time-savings for the project and a $400,000 cost savings for the Washington State Department of Transportation.

Major Elements Of This Project:

  • 1,000 drilled shafts totaling approximately 38,000 lineal feet
  • 12,442.02 square feet of noise wall that averaged 15 feet tall
  • 21,889 lineal feet of underground utilities and storm drain (excluding electrical trenching)
  • 220,000 cubic yards of export
  • The development of a State owned aggregate material source
