About

The M1 Pacific Motorway Upgrade between Mudgeeraba and Varsity Lakes includes widening a 5.7 km section of the motorway to three lanes in each direction between Mudgeeraba (Exit 79) and Varsity Lakes (Exit 85) and a fourth lane northbound between Robina (Exit 82) and The Link Way (Exit 80).

Other scope involved:

  • extending entry ramps and exit ramps to meet current design standards
  • reconstructing the Mudgeeraba Creek and Mudgeeraba Creek overflow bridges on the northbound side to better withstand flood events
  • removing the right turn movement from The Link Way off-ramp (Exit 80) to The Link Way northbound to improve safety
  • constructing a new bridge overpass for Stapley Drive, at Varsity Lakes.

Key challenges included working in a constrained corridor, live traffic environment carrying over 120,000 vehicles per day, significant rail interface with the Gold Coast Rail Line and complex bridge demolition and construction over sensitive waterways.

“This project is progressing well due to the good performance of Seymour Whyte.”

Alan Purvis, Client’s Representative, TMR, Oct 2019
