UPDATE: Work resumes to reinforce slope on US 127, traffic reduced to one lane
UPDATE: Work was temporarily stopped on U.S. 127/Signal Mountain Boulevard when geotechnical engineers from the Tennessee Department of Transportation encountered 'unexpected subsurface materials' that have caused the drilling operations to take much longer than anticipated.
On a typical workday, drill crews can complete at least five borings a day.
But the project needs a total of 19 borings to allow engineers to gather all necessary information for the permanent repair design, it is going to take more time than originally anticipated, according to TDOT spokesperson Jennifer Flynn.
Crews will continue to perform drilling operations weekdays between the hours of 9:00am and 8:00pm EDT.
Work is scheduled to resume on Monday, March 11, 2019 at 9:00am EDT, and will continue for approximately two weeks or until the drilling is completed.
During the work, it will be necessary to close one lane. Flaggers will assist with traffic control in the drilling area, between Balmoral Drive and Sunset Drive.
Traffic traveling up the mountain between the peak times of 3:00pm and 6:00pm EDT will be given priority by the flagging crews.
This work is weather dependent. Drivers are urged to be patient and to watch for workers and equipment.
PREVIOUS STORY: With rain in the forecast for Sunday, emergency work is being done Saturday to stabilize a slope on Signal Mountain.
Contractors are working to reinforce a slope on US 127/ Signal Mountain Boulevard between Balmoral Drive and Sunset Drive, TDOT spokesperson Jennifer Flynn explained.
"Once completed, this repair will further stabilize the slope while we develop plans for a permanent fix," Flynn added.
This is the same area where TDOT crews milled and paved the cracked pavement Friday.
At this time, US 127 is reduced to one lane in the area where crews are working. Flaggers are helping control traffic.
"Originally we were going to do the work via Palisades Drive near the Space House, and U.S. 127 was going to remain open, but at roughly 11:30 , we saw that the work was not progressing as we had hoped because the haul road that Wright Brothers was constructing was too soft and they could not get trucks up the haul road to the slope," Flynn said. "In light of that, we decided to close one lane above the site, remove the guardrail and work from above on US 127."
Flynn said crews plan to have the project finished by the end of the day Saturday.
