Highway 43 – final paving complete, striping begins next week
Final paving of the lane where the pipe has been installed on Highway 43 was completed last week! Most traffic loops have been reinstalled—some remain at the signaled intersections of Holy Names Drive and Furman Drive—and the remainder will be installed over the next week.
Final striping will be placed starting this Sunday night, through early August. Nighttime work hours on Highway 43 are 8 p.m. – 5 a.m., Sunday through Thursday. During work hours, one lane will be open at a time, in most areas, with flaggers guiding traffic in each direction.
Thank you to businesses, neighbors and commuters for your patience during the paving and restoration work!
Mapleton Drive pipeline activities
Auger bore at Trillium Creek - patching work
This week, crews patched over the steel plates with some temporary asphalt. This will help keep the pit secure and drivable until crews return to install the remainder of the pipe on Mapleton Drive.
Sanitary sewer relocation - mid-August
Crews are finishing up some final segments of pipe work in Gladstone, and plan to start relocating the sanitary sewer line near 4020 Mapleton Drive in mid-August, however, schedules are subject to change. The sewer relocation involves digging in the road and installing a new sanitary sewer line. To avoid service interruptions, the contractor will use a temporary bypass during the work.
To prepare for the sewer relocation work, crews will mobilize equipment along the right-of-way, set up the temporary storage area on the south side of the Water Treatment Plant site, and place tree protection fencing in the active work area. To maintain a single lane of traffic, the contractor will also add gravel along the shoulders of the existing pavement near the sewer work to temporarily widen the road.
The sewer relocation work is expected to take up to two weeks to complete. During this time, there will be a single lane closure with flaggers directing traffic. Please expect some short-term, temporary delays to get through the work zone. Please drive with caution when traveling through the active work zone and follow flaggers’ directions. Neighbors are encouraged to use Nixon Avenue to avoid traveling through the work area.
Open-cut pipeline work
Open-cut, trenched pipeline work is expected to begin after the sewer line is relocated, however, schedules are subject to change. Crews plan to start at the eastern end of Mapleton Drive, working toward Nixon Avenue.
Once crews work past the Nixon Avenue and Mapleton Drive intersection, a detour will be in place during work hours. During construction hours, residents located east of the active work zone will need to use the detour route on Nixon Ave and Cedaroak Drive.
