BAY AREA TRANSIT PLANS IN FOCUS : MUNI'S ALIGNMENT IMPROVEMENTS

Concerns regarding surface disruption at the new Third Street LRT project, a component of San Francisco Municipal Railway’s (Muni’s) Central subway, have led designers to consider deep level tunnel instead of shallow cut-and-cover excavation as originally proposed. This article looks at deep tunneling should lead to reductions in surface disruption, utility relocation, and construction time. In addition, the article relates that changes to the original subway alignment are under consideration. These may ultimately result in a two to three minute saving on passenger travel time and close to $140 million in construction costs. These savings would stem from having three underground stations instead of four, and eliminating the need for two separate portals.
