Pacific Motorway M1 M3 Gateway merge flythrough
The Queensland and federal governments are helping you to spend less time in the car and more time doing the things you love by upgrading the Pacific Motorway at the M1 M3 gateway merge.
Currently this section of the M1 accommodates almost 150,000 vehicles per day making it one of the busiest sections of the motorway in southeast Queensland.
This upgrade will increase public transport travel reliability with better connections resulting in more reliable travel times.
The installation of smart technologies known as managed motorways will more effectively manage the flow of motorway traffic ensuring that traffic keeps moving and you get to your destination on time.
We're increasing the current capacity and safety of entry and exit to the motorway by replacing the current two-lane overpass with a four-lane overpass at Underwood Road by realigning and signalizing the intersection at Eight Mile Plains State School.
Travel to and from school will be safer for your family.
A new on-ramp dedicated to buses will allow for increased travel reliability not just throughout the project zone but across the public transport network by adding up to five southbound lanes between Eight Mile Plains and Roachdale.
This upgrade increases the capacity of the M1 and offers motorists a quicker safer and less congested journey.
This 190 million dollar upgrade is currently under construction and is expected to be complete by mid 2020.
We are working hard to bring you more reliable motorway travel.
We are getting you where you need to be on time.
