I-35W Bridge Water Main Relocation Minneapolis, MN

The I-35W Bridge reconstruction was a fast track design/build project involving all utilities, gabion walls and pedestrian tunnel relocation in response to the I-35W bridge collapse in 2007.

The water main relocation involved critical path items such as contaminated soils remediation, storm sewer, water main and sanitary sewer installation. Management and coordination with several subcontractors and MNDOT was essential to ensure the bridge would be re-opened on time in the most efficient manner possible under extreme time and weather constraints.

Meyer Contracting was hired to install all of the site utilities on both sides of the bridge during re-construct.  This included all of the temporary Sanitary Sewer bypassing until replaced. This work was a 24-7 operation and completed in the winter months.

Meyer installed the largest pedestrian tunnel in Minnesota (20’ x 11’). The bridge was completed on budget and over 20% ahead of schedule.
