Soil Engineering Geoservices has started investigation and grouting works of disused mine workings for a new Skolie Burn Bridge in West Lothian.
The existing bridge, which has both weight and height restrictions, will be replaced next year.
The geotechnical work includes boreholes and remedial grouting work to be carried out as part of the £2.4M project to replace the bridge. It follows initial ground investigation works previously carried out at the site that identified potential disused mine workings beneath the site.
A West Lothian Council spokesperson said: “Local residents and those using Skolie Burn Bridge are warned to expect delays from Monday 10 September. The works are expected to last around five weeks.
“Skolie Burn Bridge is thought to have been built in the mid 1800s, with an extension added at a later date, and now requires to be replaced. The current bridge has had restrictions in place for a number of years, so is not suitable for all traffic.”
The work will take place in two phases, with preliminary grouting works set to starting this week for up to six weeks. This will be followed by the main bridge replacement works starting early 2019, which is expected to last up to nine months.
