Rainier is pleased to announce the award of the I-405 Renton to Bellevue Corridor Widening and Express Toll Lanes project.

This project represents the single largest project ever awarded to Rainier Welding and is an exciting part of our future as a major steel infrastructure contractor in the Northwest. Our team of fabricators has worked hard over the years to establish themselves as the premier sign bridge builder for the State of Washington. A joint Venture between Flatiron and Lane has chosen Rainier Welding to provide more then 50 bridges and 20 cantilevers for this project that will create express lanes from Renton to Bellevue. This is exciting news to our team of sub-arc welders and will provide more then 40,000 shop hours to our team. Thanks to Flatiron Lane, a JV,  for your confidence in us.
