The cause of the collapse of Mammoth's Lake Mary Rd. bridge remains under investigation. It was a sudden and shocking development last month when, on a Friday evening, the tunnel and bridge fell straight down on the road. No one was hurt. Today, a new bridge zooms along with completion expected before Thanksgiving.

Mammoth Town Manager Rob Clark said the construction of the new bridge moves along on track. The new structure is a metal bridge similar to what existed previously. Clark said the structure comes in sheets which are bolted together and attached to new footings.

Crews now work on a back-filling process which is very sensate and has to proceed very slowly to carefully balance out the new bridge. An engineer remains on scene to guide this process.
