Capacity Enhancement Project
Enbridge Gas Utah is replacing a section of its system in North Salt Lake City known as Feeder Line 148. Feeder lines are larger, steel pipelines that supply smaller main and individual service lines that connect to meters at homes and businesses.
Project overview
Need for the project: The Feeder Line 148 replacement project is located in North Salt Lake City on Center Street from Foxboro Drive to approximately to 300 West. This project is necessary to keep pace with increased demand for natural gas due to customer growth. It will also enhance our ability to continue providing safe, reliable natural gas service by making our system easier to monitor and maintain.
Location: This section of natural gas pipeline is located in North Salt Lake City on Center Street from Foxboro Drive to approximately to 300 West. (See map for exact route.)
Construction schedule: Crews are scheduled to start in May 2024 and finish in late fall 2024.To expedite construction, multiple crews will be working simultaneously at various locations during the project. Crews may also work at night and on weekends.
To provide room for crews and equipment, some temporary lane restrictions and road closures can be expected in work zones. Every effort will be made 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.
Questions: For questions, concerns, or additional information, email us and reference FL148.
Project updates
Nov. 13, 2024
Traffic will be closed in both directions from I-15 to 400 W on Center Street starting Friday at 9 p.m. until Monday at 6 a.m. No traffic will be allowed through. Eastbound-only traffic from Redwood Road to 400 W will also be in effect during this period. Drivers are advised to avoid the area if possible and follow VMS boards and detour signs.

Construction process
Enbridge Gas Utah and our contractor, Canyon Pipeline of Phoenix, AZ, are committed to completing this project safely and on schedule while minimizing as much as possible any inconvenience to local businesses and residents. To accomplish this, some work may be performed at night and on weekends. This will reduce impacts on morning and evening commutes. We will adhere to all county noise-reduction ordinances. Canyon Pipeline has more than 40 years’ experience in 39 states building pipelines in urban settings.
Construction zones
For pipe buried beneath streets or highways, construction may require intermittent closures of one or more lanes of traffic. Driveways also may be occasionally blocked by excavation work, otherwise they will be plated to maintain access during business hours and at night and on weekends.
Before construction starts in front of any home or business, a representative will contact the owner or resident to discuss options for maintaining driveway access. Signs notifying the public that businesses remain open during construction are available.
To finish construction on schedule and as quickly as possible, the project is divided into sections, or "spreads." This allows multiple crews to work simultaneously at different locations. Work zones can range from a single intersection to several blocks long. At any one location the amount of time to cut pavement, install new pipe and replace asphalt can range from several days to several weeks.
The public can do its part to ensure construction proceeds safely and on time by finding alternative routes, driving carefully in construction zones and keeping children away from construction sites.
Enbridge Gas Utah works closely with city and state transportation officials to ensure safety and minimize inconvenience to drivers and pedestrians. However, for public safety it may be necessary to temporarily close streets and sidewalks or restrict vehicle and pedestrian traffic. As mentioned, driveways may occasionally be blocked by excavation work. We will make every effort to keep these inconveniences as brief as possible. Your patience is appreciated.
If you have questions or concerns, do not hesitate to contact us.
Steps during construction
Following are brief descriptions of the steps involved in pipeline removal and construction:
- Locate buried utilities - The area below city streets can be a maze of underground utilities. To avoid damaging these facilities, a procedure known as potholing is used prior to trenching to identify the exact vertical and horizontal location of existing infrastructure, including the pipeline to be replaced.
- Move existing utilities - Before trenching (see next step), any utilities that cross the new pipe running line may be moved to a lower depth. This will minimize the risk of interrupting water- or gas-service to individual homes or businesses once actual construction begins.
- Dig trench - After known utilities in the trench zone are located, the pavement above the existing pipe is cut and removed. Then equipment is brought in to dig the trench. The depth of the natural gas pipeline trench will be determined by the location of the existing pipe and other utilities. As the trench is dug, the soil is loaded into trucks and hauled away for disposal in a designated landfill.
- Directional bore - At some busy intersections, most water crossings and under major roads, instead of trenching, crews will install pipe by boring horizontally underneath the road, stream or canal. The boring machine drills a hole from one side of the road or stream. Pipe is strung on the other side and then pulled back through the hole.
- Deliver and "string" new pipe - New pipe is manufactured and inspected to ensure it meets industry and federal safety standards. Pipe sections are then delivered by truck to the construction site where they are placed end-to-end (or "strung") on skids adjacent to the trench. If necessary, a hydraulic machine bends pipe sections to fit around obstacles or conform to the direction of the trench.
- Weld new pipe together and coat - Welding crews join the sections of pipe together into a continuous length. Each welded joint is visually inspected, x-rayed and then coated for protection.
- Lower pipe into trench - Using one or more pieces of equipment, crews lift and then carefully lower the welded sections of pipe into the trench. Final welds are made to "tie-in" any unconnected sections.
- Backfill trench - Under streets, in place of the removed soil, a mixture known as "flowable fill" is used to backfill the trench. In other areas, the original soil is replaced.
- Pressure test new pipe - After it's buried and before it's put into service, the entire length of new pipe is hydrostatically tested to ensure the integrity of the system. This is done by filling the pipe with water, pressurizing the system above its maximum operating conditions and holding the pressure for a specified time. The pipe is drained, cleaned and dried before it is put into service.
- Clean-up and restore ROW - The final step is to repair the surface over the trench. If necessary, fences or sod may also be replaced.
Pipeline safety
We take safety seriously. Since its founding in 1929, our company and its affiliates have engaged in every phase of natural gas service, from production and gathering to transportation and distribution. During that time, while delivering the clean and efficient natural gas our customers rely on daily for their comfort and livelihood, we have earned an enviable record for safety and reliability.
