The expanded line will connect the Theater District, Old City Hall, the Stadium District, Wright Park, and major medical facilities before reaching its Hilltop terminus.

Shannon & Wilson completed final design for the project, which includes an expanded pile-supported maintenance facility, power station foundations, and a 22-foot high retaining wall. We also produced specifications for foundations, earthwork, and instrumentation.

The new rail is atop a 200-foot-high steep slope with a history of landslides.  Preliminary design performed by others recommended mitigation to reduce potential for deep landslides.  By studying the geology and using a coupled seepage-stability analysis, Shannon & Wilson demonstrated that the slope meets stable criteria for deep-seated landslides, eliminating significant mitigation costs.

Service is targeted to begin in 2022.
