Metro Link Extensions

Project Description

  • - St. Louis Co., MO & St. Clair Co., IL
  • - Bi-Sate Development Agency

The Sterling Company performed all surveying for the eighteen-mile extension of the light rail system from East St. Louis to Scott AFB. Subsequently, we were selected to perform the same work for the eight-mile, $230,000,000 extension through some densely developed areas of suburban St. Louis County. Work on both projects included survey calculation and construction layout for electrical lines, tracks and ballast, and production of as-built drawings. The St. Louis County extension included complex work for the construction of tunnels needed to separate light rail lines from street and pedestrian traffic.
