A new £1.5M project has been commissioned by Transport Scotland that will involve the replacement of an existing sub-standard bridge, which supports the A887 near Glenmoriston.
Work to replace the existing bridge, located approximately 15 kilometres west of Invermoriston, will begin on Monday 29 March for up to seven months. The new box culvert structure will carry the A887 trunk road over the Allt na H-Innse Beag burn, which flows into the River Moriston.
The existing bridge, built in 1948, is in poor condition and needs to be replaced for the safety of road users. The replacement structure has been designed to last for 120 years and will be constructed approximately 10m east from the existing bridge. The new structure will enable the A887 to be widened to a minimum of 6m with 1.5m verges at either side. New safety barriers will also be installed as part of the works.
The project is to be carried out through the summer months to avoid any environmental disturbance associated with the watercourse and the surrounding area.
To allow installation of the new culvert, a temporary traffic signal-controlled diversion road will be constructed next to the site, allowing A887 traffic to be maintained with minimal disruption during the project. A reduced speed limit of 30mph will be implemented on the route to protect operatives and road users alike for the duration of the construction period. Traffic lights will be then used to control the flow of traffic once the temporary diversion road is operational.
Consultation has been carried out with local businesses, emergency services and the local authority to inform them of the project and the traffic management arrangements that will be in place.
Strict physical distancing protocols, in accordance with Scottish Government COVID-19 guidance, will be implemented to protect operatives, such that they remain safe at all times.
Commenting on the project, Eddie Ross, BEAR Scotland’s North West Representative said: “This £1.5 million project is vital, ensuring that the A887 trunk road remains a safe and reliable route for motorists. Our team has designed the project to include a temporary road that will be constructed next to the site, ensuring that the A887 remains open during the works with minimum disruption caused.
“The current structure is in poor condition and this is why it is to be demolished and replaced with a new reinforced concrete box structure, capable of withstanding modern traffic loads. The intended life span of the new structure is 120 years and it will be a stronger, wider and a more reliable structure for road users.
“Due to environmental constraints associated with the watercourse and the surrounding area, various key construction activities can only be undertaken during the summer months. Our teams will do all they can to complete the project as quickly and safely as possible, and will work to minimise disruption wherever they can.
“We encourage all road users to adhere to any signs or traffic management that is in place for their own safety as well as that of our teams, and remind them to plan ahead and leave some extra time for their journey.”
