1500 South Road Closure Update
The intersection of 1500 South and 500 East will remain the contractor’s primary work focus today and into next week. The intersection is open to through traffic, but the travel lanes are narrower and require extra caution—especially given the amount of north–south traffic on 500 East. Flaggers will be present to guide vehicles safely around the small work zone. Please slow down and watch for construction workers and equipment when approaching the intersection.
A two‑day full closure of 1500 South between 500 East and 400 East will be required while the contractor repairs a manhole and replaces a large asphalt section surrounding it. The asphalt patch will span nearly the full width of the roadway in a north–south direction. This closure will likely occur Tuesday and Wednesday of next week, but could shift to Wednesday and Thursday. Once the schedule is confirmed, the newsletter, website, and flyers will be updated with the closure dates and detour route.
If the overall project schedule holds, the contractor plans to remove the by‑pass pumping operation toward the end of next week. The by‑pass system—located near 50 West by the sewer lift station—has been the reason for the long‑term closure of through traffic on 1500 South during this pipeline rehabilitation project. Removal of the above‑ground pipes and reopening the roadway depend on the pipelining work and the by‑pass pumping phase being fully complete.
Road closures and detours on 1500 South are nearing completion. We appreciate your patience and cooperation throughout this important utility project. Thank you again.
The map below is the current detour route. A new route will be provided for the 1500 South, 400 East to 500 East closure, once scheduled.

This photo shows the pipelining process used to install a new liner inside the existing sewer pipe. On the left, a flatbed truck carries folded stacks of the liner material. The liner is fed into a long white box trailer, where it is prepared for insertion into the sewer system. From there, the material is guided into the existing pipe through a nearby manhole.
Once inside the sewer pipe, the liner is expanded so it fits tightly against the interior walls. Using a proprietary steam‑curing process, the material hardens in place and forms a durable protective barrier inside the existing sewer line.
For this phase of work, the contractor is primarily installing the liner from within the Timpanogos Special Service District (TSSD) campus, moving northwest toward the manhole at 500 East and 1500 South.

1500 South Road Closure Update
Manhole work at the east edge of the R&D excavation site (258 East 1500 South) is now complete. Most of 1500 South is open to through traffic, except for the area near 50 West where the by‑pass pumping operation remains in place. Drivers will still see traffic‑control panels indicating locations where large steel plates cover manhole openings.
On Tuesday, September 8, the contractor will be working in the intersection of 1500 South and 500 East. The intersection will remain open to traffic in all directions, but flaggers will be present to guide vehicles safely around the small work zone. This phase of work is expected to continue through Monday, September 14.
If the schedule holds, the contractor plans to remove the by‑pass pumping operation toward the end of next week. This is dependent on the pipelining work being completed and the by‑pass phase finalized.
Road closures and detours on 1500 South are nearing completion. We appreciate your patience and cooperation while this important utility work has been underway. Thank you again.

1500 South Road Closure Update August 24 - Sept. 2, 2026
The next phase of pipe lining will take place between approximately 250 East to 150 East on 1500 South. As there are no signs or buildings to help identify the work area, the following landmarks may be helpful reference points. The west end of the work area is near the south entrance to the Alpine School District bus yard parking lot on 1500 South. The east end is approximately at the east edge of the R & D Excavation property on the south side of 1500 South.
The road will be closed to through traffic during this phase of the project. Traffic to and from businesses and homes within the closure will be facilitated. However, brief delays may occur depending on the work taking place at any given time. The intent is to avoid blocking driveways or access points for extended periods whenever possible.
Please do not attempt to cut through the road closure areas, as these sections are an active construction zone and will have heavy equipment. If you live or work within the construction zone and need to enter the area, please drive slowly and watch out for construction equipment and workers. Your cooperation will be greatly appreciated.
*Updated* Road Closure Information Detour Route
The road closure at approximately 50 West, where the black bypass pipes cross 1500 South and create a physical barrier, is scheduled to remain in place through Wednesday, September 15. This is a change from what was originally reported and will result in a two-week delay in reopening the road at this location
We apologize in advance for this delay. This is a complex project, and several circumstances that could not have been anticipated were discovered after the project began. The contractor is working 24/7 to complete this phase of the project so 1500 South can be re-opened.
We apologize again and recognize this has created challenges for you, your clients and employees.

These are some images of equipment that the contractor is using to install the lining in the existing pipe. The lining that goes into the pipe is something like a thick white fibrous blanket. The liner is installed into the existing pipe and then heated, which cures the liner and makes it rigid and protective. The process is referred to as Cured in Place Pipe or "CIPP". Here is a link from the contractor's website that gives a brief overview of the pipe lining process.

1500 South Road Closure Update August 24 - Sept. 2, 2026
Below is a copy of a flyer that was distributed on August 20, 2026.
This last week the contractor has been working from about 250 East over to 500 East, lining that section of pipe. On Monday, August 24th, crews will begin lining another section of pipe.
The next phase of pipe lining is between approximately 250 East to 50 West on 1500 South. The road will be closed to through traffic during this phase of the project. Traffic to and from businesses and homes within the closure will be facilitated. However, brief delays may occur depending on the work taking place at any given time. The intent is to avoid blocking driveways or access points for extended periods whenever possible.
Please do not attempt to cut through the road closure areas, as these sections are an active construction zone and will have heavy equipment . If you are local traffic and need to inter the active construction zone, please drive slowly and watch out for construction equipment and workers. Your cooperation will be greatly appreciate

The contractor has removed the steel plates in several locations and backfilled the by-pass pipe trench with fine gravel. This was done to reduce noise and provide a smoother transition over the buried pipes.

Part of the pipeline liner installation process includes the use of a vacuum truck. The vacuum is used to remove any remnant debris in the existing pipe that was not removed previously or that may have been inadvertently introduced into the pipe system during the lining process. The vacuum is loud and continuous when in use. For the next week the vacuum truck will only be utilized during the daytime hours. However, starting Wednesday, August 26th, the vacuum truck will be used both day and night to keep the project on schedule. We apologize in advance for the disturbance this will cause. The vacuum truck will be working at the various manhole locations along 1500 South and may return to a location that was previously serviced.

As indicated in the flyer, the sewer pipe lining is taking place between manholes and will shift from week to week. The below-mentioned flyer is for the effort through Saturday, August 22nd. Starting Monday, August 24th, a different section of pipe will be lined along1500 South and run through Wednesday, September 2nd. That phase will impact 1500 South from about 50 East to about 300 East, which includes the intersection at 1500 South and 100 East. Another flyer with an updated map and detour route will be delivered this Thursday, August 20th for the next phase.
From the Work Zone
For the last month the contractor has been setting up the sewer line bypass system along 1500 South from approximately 50 West to just immediately west of the Frontrunner track at the main entrance gate of the Timpanogos Special Service District. The large black plastic pipes that alternate between the south and north side of 1500 South are being used to bypass about 10 sewer manhole locations.
Using a series of large mobile pumps and black plastic pipe, the bypass system will temporarily redirect existing sewer flows from the west end of 1500 South around the section of sewer line being repaired and deliver the flow to the wastewater treatment plant. This allows Insituform to drain, clean, and repair the existing sewer line, including addressing any corroded concrete or exposed rebar, in preparation for the new plastic liner. These project phases include building the bypass system, preparing the pipe, and installing the new liner.
Steel plates have been placed over the black pipe which has been placed in a shallow trench to allow for more streets to remain open and for drive access to businesses and residences as needed.
