The new £1 million bridge will be constructed using a single-span galvanised steel structure and has been designed to allow all road traffic to cross, with no weight restrictions.
The site team will be working around a four metre vertical face on the east embankment to construct new abutments, pouring 100 cubic metres of concrete.
The design also includes improvements to drainage to defend the bridge from severe weather damage in the future.
As with all of its projects, Morgan Sindall has taken steps to ensure that no damage is caused to the surrounding environment. Measures have been taken to ensure debris from the construction process does not fall into the Black Water and dry stone walling, due to be dismantled during the build, will be salvaged and reconstructed once the bridge is in place.
Morgan Sindall’s area director for infrastructure, Robert Ogg, said: “The C446 road provides a vital link between Alyth and the A93 to Glenshee and the local communities come to depend on the infrastructure network so heavily, often without noticing how vulnerable it can be.
“We are acutely aware of this reliance and are proud to be designing and building a new bridge to restore this critical access; our message to the many people who would usually use this route is that the end is in sight.”
