Infrastructure Australia has announced $2 billion worth of funding for planned upgrades to the Bruce Highway, south of Cairns, and the M1 Pacific Motorway.

The upgrades to the M1 include widening of an 8.5 kilometre stretch between Eight Mile Plains and Daisy Hill and an extension of the South East Busway to the Springwood bus station, providing capacity for 50,000 extra daily trips by 2041. . 

Infrastructure Australia chief executive Romily Madew says increasing congestion on the M1 is causing a high number of accidents and the planned upgrades will improve travel times as well as road safety.
