The Salt Lake intersection of 200 South and Main, closed to traffic early Wednesday, will remain closed until Aug. 1, according to a revised light-rail construction schedule.

The Utah Transit Authority, which delayed some downtown work to allow for better traffic flow, had planned to close 200 South for six weeks to relocate utility lines, open it briefly, then close it again to install light-rail tracks. Now, UTA and its contractor, Gilbert Western Corp., have decided to do all of that work at once."When UDOT shut off I-80, it put a lot more traffic downtown. We were concerned with that," said Ron Holt, UTA's resident engineer for the central business district. "The (original) intent was to close both 200 and 300 (South) at the same time, but we haven't done that and, of course, that delayed the schedule."

The intersection of Main and 300 South was open to one lane of traffic in each direction Wednesday and soon will be open altogether as utility work is completed. It will then be closed for another six weeks, Aug. 1-Sept. 15, when 200 South is reopened.

The intersection of South Temple and West Temple is due to open June 1, and the intersection of 700 South and Main should open June 15. The intersection of 300 West and South Temple will not be closed, but traffic will be severely restricted there between Aug. 15-Nov. 15.

All work on 700 South and 200 West is to be finished by July 15. All work on Main is to be completed by Sept. 15.
