The Governor's Bridge road junction and hairpin bend are part of the Snaefell Mountain Course used since 1920 for the Isle of Man TT and from 1923 for the Manx Grand Prix Races.
The new link road also created a small wooded glen on the site which is known for its distinctive horse-chestnut trees.
During October 2007 the Isle of Man Department of Transport began road widening at Braddan Bridge, further around the Mountain Course exiting Douglas, additionally creating a roundabout.
This road widening scheme occurred between February and April 2008,[4] with the removal of trees on the Bemahague Estate (which includes Government House, the official residence of the Lieutenant Governor of the Isle of Man) and the creation of a small mini-roundabout.
Further work by the Isle of Man Department of Transport in July and September 2008 included the installation of a storm drain and the completion of the mini-roundabout.
