August 2018 – Road & Trail Conditions

[Erin Potter]

Hi all,

Starting off the August thread with an update on South Four Mile Run Trail, between S Glebe Road and with Water Pollution Control Plant.

From my inbox:
“As part of the South Four Mile Run Sanitary Sewer Relining project, Arlington County will reline a 50 year-old 48/54-inch sanitary sewer line on South Glebe Road from West Glebe Road to the Water Pollution Control Plant (530 31st Street South) on South Fern Street. A CCTV inspection conducted in the fall of 2015 revealed that the sanitary sewer pipe had moderate-to-severe deterioration, including: corrosion, small holes, infiltration of roots and reinforcing steel exposed with rusting. The purpose of this project is to extend the life of the pipe using a trenchless rehabilitation method, known as cured-in-place pipe (CIPP). Arlington County will use county contractor AM-Liners East Inc. to perform this work.

Location: East bound side of S Glebe Rd from W Glebe Rd to the Water Pollution Control Plant (530 31st St S) on S Fern St
Duration: Summer 2018 to winter 2018/19

The CIPP process requires a temporary bypass to be installed prior to the installation of the liner to ensure no disruptions in service. Large pumps and pipes associated with the bypass will be installed near the trail at S Four Mile Run Dr and S Cleveland St and will run continuously to the Water Pollution Control Plant located at 530 31st St S. Traffic may be impacted on S Glebe Rd and on the S Four Mile Run bike trail at times when the contractor is installing the temporary bypass system. Due to the length of the project (5,900 linear feet), there will be some sections where the bypass is above ground.

The process used to cure the pipe requires crews to work around the clock. The pumps and boilers will run constantly during the curing phase. Each pipe segment normally takes between 24-36 hours to cure.

Additionally, a 60-inch section of pipe on S Arlington Ridge Rd and S Joyce St will be removed and replaced. The right east bound lane on S Glebe Rd will be closed during the excavation and replacement of the pipe. A new traffic pattern will be in place with warning signs. This work is estimated to take approximately 45 days to complete and the start date will be determined upon the installation of the bypass. Work hours will be Monday through Friday from 9 a.m. to 5 p.m.

Residents should expect inconveniences such as parking restrictions, traffic detours, street closures, dust and noise. We will make every effort to minimize any inconveniences and we greatly appreciate your patience and understanding during this time.

For more information, please visit the project website: https://projects.arlingtonva.us/projects/4mr-sewer-relining/.

If you have any questions, please contact our construction manager, Hisham Wahdan at Hwahdan@arlingtonva.us or 703-228-7628 between the hours 7 a.m. to 3 p.m. For any after-hours emergency, please call our 24-hour Water Control Center at 703-228-6555.

Your understanding and cooperation during this period is greatly appreciated.”

The sewer bypass project on Four Mile Run continues. Pipe has been laid out all the way from the S/W Glebe intersection to Eads.

Where the pipe crosses the trail between Mt Vernon and the treatment plant, they’ve built THIS to navigate over it. It’s solid, it has stripes and a non-skid surface, and huge signs warning you of its presence. When they’ve gone to such lengths to keep the trail open when possible, it’s hard to complain about the periods when it’s not.

The section between S/W Glebe and S Troy is still detoured to the sidewalk. People seem to be coping with it, despite it being so narrow. Stay safe.

Overall they’ve done a great job with signage, but the section along Glebe where the trail is right against the road is is VERY narrow with the pipe taking up about 1/3rd of the trail. It can feel a little scary when there is a bike coming the other direction and there is heavy car traffic. Otherwise I have no real complaints.

Rode this yesterday and really enjoyed the ramp. The trail really is narrow in those places where the pipe is sitting on it. And right at the sidewalk detour an e-roadbike passed me at double my speed with no warning and less than a foot of clearance. This tool has done this before, but this time I was able to catch up with him at the light so at least he is aware of what he is now since he apparently did no know.

Caught some air then?

I could do without the cones next to the pipe narrowing the trail even further. How about putting the cones on top of the pipe, leaning against the wall?

“Wheeeeeee!”

Checked first to make sure no one was coming, and also that the lip wouldn’t flat me.
