Welcome to the Questar Gas Salt Lake City System Improvement Project Website

In 2014, Questar Gas began a multi-year infrastructure-improvement initiative to replace several thousand feet of aging natural gas pipelines under major streets in and around downtown Salt Lake City. These improvements are necessary for Questar Gas to keep pace with growing customer demand for natural gas, maintain overall system integrity and continue providing safe and reliable service.

Pipeline replacement work is underway or is planned at the following locations and, weather permitting, for the specified times (see map):

400 East between South Temple and 400 South
200 South between 200 West
and 400 West
400 South between 50 West and 200 West
500 South between Main St. and 200 West
Harrison Blvd from 7th St. To 2nd St. (Ogden)
300 East between 2100 South and 3300 South

Sept. thru March 2016

Resume in spring 2016

Jan. thru June 2016

Sept. thru Jan. 2016

Feb. thru Dec. 2016

Questar Gas is committed to completing this work as quickly and with as little inconvenience to local businesses and residents as possible. These projects may involve some nighttime and weekend work. To provide room for crews and equipment, some temporary lane restrictions, especially at intersections, will be necessary. Watch this site for the latest traffic information. Please drive carefully and obey all signs and flaggers. To avoid congestion in construction zones, motorists are advised to use alternate routes when possible and to allow plenty of travel time to get where they're going. Questar Gas crews will make every effort to maintain access to businesses and driveways in construction zones at all times. No interruption to residents’ natural gas service is anticipated during this project. We appreciate your patience.

These projects are part of a multi-year effort by Questar Gas to maintain system integrity by replacing aging sections of pipe throughout Utah. Since 1995, the company has successfully replaced nearly 150 miles of high- and intermediate high-pressure pipe installed prior to 1970. Future system upgrades in Salt Lake City are planned for North Temple, South Temple, 2200 West, 1300 East, 300 East and Sunnyside Avenue. The company will announce the start of these projects when schedules are determined.
