Motorists can expect interference at three Salt Lake County intersections until construction projects are completed, the Utah Department of Transportation says.

Weather permitting, workers will replace a deteriorating irrigation culvert that crosses 35th South just west of 32nd West, April 18-21. Traffic on 35th South will be restricted to one lane in each direction with no left turns allowed. Traffic on 32nd West will not be restricted.Work also is being done at 35th South and 56th West, where traffic is restricted to one lane in each direction on all four legs of the intersection. Left turns are prohibited. Work is expected to continue at the intersection four more weeks.

This work is part of a $1.3 million project to improve intersections, upgrade traffic signals and make safety improvements along 35th South from 2820 to 56th West.

Today and April 17, Third West will be closed at the railroad crossing at 2230 South from 8 a.m. to 5 p.m. while the Denver & Rio Grande Western Railroad replaces tracks at the crossing. Traffic will be detoured to other local streets.

Beginning April 18, Third West will be restricted to one lane in each direction while workmen improve the highway approaches to the railroad crossing. This project will take about two months and is expected to cost $75,000.
