Description
The Stadium Segment of Light Rail Transit 416.2 is a $65 million project adding 3 miles of new LRT tracks along with five stations—three at-grade and two elevated—plus significant track bridges and a park-and-ride lot. SB&O oversaw boundary retracements, topographic surveys, and construction staking for rough grading, track alignment, water, sewer, and retaining walls. This included setting up abutment and pier locations for seven bridges spanning a total of 11,700 feet. The firm also handled utility relocation staking and final property corner re-establishment, ensuring the transit expansion integrated seamlessly with existing infrastructure.
