Kirkby Malham Bridge Widening

• Client: North Yorkshire County Council
• Location: Kirkby Malham, North Yorkshire
• Value: £229,500.00
• Period: November 2018 – February 2019

Kirkby Malham Bridge is a single arch masonry Grade 2 listed bridge (which spans Kirkby Beck) that required widening for safety reasons. There were no existing footpaths on the bridge but the widening allowed for footpaths to be incorporated. The bridge is at the bottom of an incline, just adjacent to the main crossroads in the centre of the village, and there had been accidents in the past due to the narrowness of the bridge and poor sight lines at the junction. The bridge parapets had also been impacted and damaged by errant vehicles.

GENERAL OVERVIEW

• Installation of a temporary bridge supplied by North Yorkshire County Council
• North Yorkshire County Council provided the arch and abutment stones which were installed by our masonry sub-contractors, Pinnacle Stonemasonry
• The works were carried out during the winter so a temporary tent arrangement was made to protect the works. No masonry work was carried out in low temperatures
• The works were carried out under a 2-way traffic management system during the contract period
