In the North of the historic city, Balfour Beatty Civil Engineering will build larger park-and-ride facility at Lansdown.
Welsh civils contractor Alun Griffiths drives off with the Old Down upgrade project in the south west, while local Gloucestershire contrator E R Hemmings Communications will build in extra capacity and a new building at Newbridge park-and-ride scheme in the west.
The projects form part of a £45m local transport spending package to upgrade links and cut congestion in the tourist city.
