A91 /140 – Dollar Bridge, Bridge Strengthening Contract


Description of the goods or services required

An inspection of the Dollar Bridge followed by a structural assessment found that strengthening works were required to increase the structural capacity of the bridge.

The bridge carries the A91 over the Dollar Burn in the centre of the town of Dollar in Clackmannanshire. It is a single 6.75 metre span masonry arch. The arch, abutments and parapets are constructed in good quality ashlar masonry, which is generally in fair condition. The date of construction is unknown. The carriageway over the bridge is straight and therefore there is no skew.

However, the carriageway rises notably over the crown of the arch. At each of the four corners of the bridge there is a junction with a side road off the main A91.

The proposed works comprise excavation of the existing fill above the arch and replacing it with mass concrete backing.

Works will also be required to raise the height of the Parapet walls to conform to current standards.

Works to scour damage at both abutments near the downstream end is required. Re-pointing and stonework repairs are to be undertaken to the arch barrel.

Temporary traffic management, in the form of a single lane road closure, is required to facilitate the works, to control traffic and provide access to the site. Full road closure will not be permitted to take place.
