TEMPORARY traffic lights have been erected on the A72 road west of Peebles after deterioration to a retaining wall was discovered.
Share this image
The westbound lane of the road will be closed at Neidpath from today (Friday 6 February) for safety reasons.
This will allow the wall to be assessed by Scottish Borders Council (SBC) and determine the extent of the deterioration.
Following this assessment, the Council will develop options and identify costs of repairing the wall.
At present, there are no timescales on how long the lane closure will be in operation, with further information available after the assessment of the wall has taken place.
However, the Council does recognise the inconvenience to drivers and is working to resolve this issue as soon as possible.

Projects possible thanks to federal Gas Tax Fund
February26, 2015 ThunderBay, Ontario Infrastructure Canada
Residents of ThunderBay are benefitting from a series of local infrastructure improvements, thanks to contributions from the federal Gas Tax Fund. Joint investments from the federal and municipal governments supported a number of projects in 2014, including local road infrastructure rehabilitations, railway crossing upgrades, and the design of a new retaining wall on one of the city's most prominent streets.
In total, six local roads were improved throughout the city. Cornwall Avenue was completely reconstructed to include the addition of new sewers and water mains. Leslie Avenue and Lithium Drive were both repaved, as were Arthur Street, Begin Street and Edward Street; the latter will also boast new curbs, sidewalks, street lights, water mains and storm sewers in spring2015. The newly rehabilitated roads will help improve traffic flow and increase safety, while sewer upgrades will contribute to protecting the environment and residents' well-being.
Meanwhile, upgrades were also completed on the Canadian Pacific (CP) Island Drive and the Canadian National (CN) Mountdale Avenue spur track crossings. Work included the addition of new rail and new asphalt intersection surfaces to improve rideability and ensure safe and smooth travel for trains passing through the city. Planning and design has also begun on the replacement of a 100-year-old retaining wall on High Street. Replacing the wall will reduce long-term maintenance and repair costs while ensuring motorists' safety.
"Our Government is pleased to provide ThunderBay with flexible infrastructure funding that allows the city to support a multitude of projects. These local road and rail improvements, made possible by the Federal Gas Tax Fund, will ensure that drivers and train passengers can enjoy safe and smooth travel for years to come. The federal Gas Tax Fund will continue to aid municipalities like ThunderBay, and continue to generate economic growth across Ontario."
- The Honourable Greg Rickford, Minister of Natural Resources, Minister for the Federal Economic Development Initiative for Northern Ontario and Member of Parliament for Kenora
"We are pleased that the Federal Government is supporting our efforts to address our City's infrastructure needs. Improvements to infrastructure such as bridges, sidewalks, street lights and water mains play a critical role in the vitality of our City and contribute to quality of life for citizens, as well as visitors. This funding represents an ongoing investment in a healthy, vibrant, connected and strong City."
- His Worship Keith Hobbs, Mayor of ThunderBay

A proposed upgrade and repair project on Alley Street in Alma has been estimated at $250,000, according to engineering reports given to the city council.
The project would involve road, retaining wall and sewer line work in close quarters with neighboring property owners.
Its not a typical job by any means, said Lisa Fleming, an engineer employed by Ayres Associates of Eau Claire, Wis.
The project also would involve obtaining work easements from a couple of property owners before the city could take construction bids. City officials plan to handle easement talks. Fleming said it was possible the city could award a bid contract in April.
Retaining wall work would involve use of manufactured stone blocks resembling limestone. Wall work was estimated at $100,000.
The city council in December approved spending up to $20,000 for Ayres Associates to engineer a wall design. Alderman Gary Ruff voted against it and Alderman Dave Earney abstained.
Other 2015 street projects under consideration were Cedar Street from Hwy. 35 to Second Street, and resurfacing of the south city boat-landing ramp.
Sealcoating of Vista Drive and River Street also were on the agenda. Cedar Street needs to be studied first, because it has a cement storm sewer running under it.
Kyle Busch, center, is taken to an ambulance on a stretcher after he was involved in a multi-car crash during the XFINITY Series race at Daytona International Speedway on Saturday.
The aftereffects of Kyle Buschs violent crash into an inside concrete retaining wall at Daytona International Speedway last weekend continued to ripple through the industry Tuesday, with two major track operators announcing plans to do more to protect drivers.
International Speedway Corp., the parent company of Daytona International Speedway and 12 other tracks, announced it is developing a significant plan for the installation of additional impact-absorbing technologies including but not limited to SAFER barriers (Steel and Foam Energy Reduction).
The announcement came just hours after Busch, 29, was released from Halifax Health Medical Center in Daytona Beach on a stretcher and flown to a hospital in Charlotte, North Carolina.
Busch had surgery at Halifax on Saturday night after suffering a compound fracture of his right leg and a fracture to his left foot when his No. 54 Toyota slammed into a section of wall without SAFER barriers during an Xfinity Series race.
His injuries prompted an immediate call for enhanced safety measures from drivers, fans and others, who stated they couldnt understand why all tracks werent already protected by shock-absorbing systems, such as the SAFER barriers.
ISCs plan will begin with its two superspeedways, Daytona and Talladega, ISC President John Saunders said in Tuesdays statement.
We will utilize all available tools to ensure the safety of the drivers and our fans. It will remain our top priority.
A thorough review of our other ISC facilities will continue with the focus to prioritize each tracks most critical areas first, Saunders stated. This includes but is not limited to our upcoming races at Phoenix International Raceway and Auto Club Speedway in Fontana, California.
Atlanta Motor Speedway also announced it would expand its use of impact-absorbing barriers this week, before all three major NASCAR series are scheduled to race on Saturday and Sunday.

Tracks add barriers after Busch crash
Chris Sadler is pictured digging out the dry stone wall at Froghall.
VOLUNTEERS have been learning the traditional skills of drystone walling to help repair a route which could soon become a scheduled ancient monument.
The Cauldon Plateway was the forerunner of todays railways and would transport raw materials in horse-drawn trucks, guided by metal rails on the ground.
Now part of the old line by Froghall Wharf, in the Moorlands, is being used as the backdrop for training courses.
A group of volunteers spent two days there last week, digging out a stretch of the retaining wall along theroute and repairing its stonework.
The wall, which dates back to the 18th century, had become almost hidden under mounds of earth.
Waller and advanced craftsman Andrew Brown-Jackson demonstrated the techniques.
He said: We havent been allowed to use any stuff thats not of the same age.
Much of the material used for the retaining wall here is grit stone.
The drystone techniques were originally used thousands of years ago and the traditional approach has changed little since then.
