Burchills were engaged by Lendlease Engineering to undertake pre and post construction surveys for M1M3 upgrade project.
The Pacific Motorway Upgrade – M1/M3/Gateway Merge Project scope includes:
- Utilising the existing pavement to provide four lanes on the Pacific Motorway under the Gateway Motorway (M2) Overpass, merging back to three lanes prior to the Gateway Motorway and Pacific Motorway merge.
- A concrete barrier between the north and south bound carriageways with pavement widening on southbound carriageway to provide for the five lane cross section from the Gateway Motorway merge to Rochedale Road – approximately 2.5 kilometres.
Replacing the Underwood Road overpass with a new bridge to accommodate five general traffic lanes in both directions (southbound and northbound carriageways) and a new bus on ramp and an access road from School Road under the bridge.
