Stuart Mesa Second Track - Oceanside, Calif.
The North San Diego County Transit Development Board awarded Kiewit a $3.7 million contract to install two miles of secondary mainline track. The project made it possible for trains to be shifted to and from the newly completed Stuart Mesa maintenance facilities. This project also included the construction of a high speed turnout — the first 90 mph turnout in North America.
The project's main scope of work included installing tie rail and two #24 main power turnouts, excavation and demolition of signal pole and abandoned spur track, placing new subballast and ballast, and constructing a subdrain system and retaining walls.
