The bridge had a 10ton weight limit which restricted the size of plant we could use, and the canal needed to be kept open to allow boating traffic to continually navigate the canal.
The four wingwalls had to be tied to each other buy drilling right through the bridge from one side to the other and installing 6 stainless steel tie-bars and pattress plates. The vast majority of the brickwork was then re-pointed with NHL5 lime mortar and new coping stones made and installed on the parapets.
The entire road surface and bridge deck was removed which involved excavating around live Gas and Water services. A new reinforced concrete support slab was then installed followed by new kerb drainage and tarmac road surface.
Using specialist scaffolding, drilling rigs and floating plant the scheme was delivered on time and on budget to the delight and satisfaction of both Canal and River Trust and the County Council.
