Construction of the Utah Transit Authority's light-rail mass transit system has closed a section of 9400 South in Sandy through Saturday afternoon.

The road was closed off at the railroad crossing, at about 160 East, early Wednesday. The street will remain blocked off at the tracks until 4 p.m. Saturday.UTA suggests motorists use 9000 South as an alternate.

The 15-mile rail transit system, from 10000 South in Sandy to the Delta Center in Salt Lake City, is scheduled to open by March 2000.
