FULLARTON-GLEN OSMOND ROADS INTERSECTION UPGRADE

LOCATION Eastwood, SA
CLIENT Department for Infrastructure and Transport c/o SMEC
DESCRIPTION Main intersection upgrade
PROJECT PERIOD 2020-2023
PROJECT VALUE $35M

Fullarton Road and Glen Osmond Road are major traffic routes and primary freight routes linking commuters, businesses, and freight to key activity centres with traffic of 58,000 vehicles per day. The intersection was experiencing heavy congestion, with competing traffic movements and network constraints leading to increased travel times and risks to safety. The upgrade improved travel times and road safety, increased intersection capacity, and enhanced network reliability.
MLEI undertook the civil engineering which included lane widths, curves, corner turn paths, pedestrian ramp, acquisition lines, impacts to properties, drainage, and constructability.

The right turn lane from Fullarton Road South to Glen Osmond Road East was introduced after commencement of the detailed design to satisfy certain stakeholder requirements. In parallel with the detailed design, MLEI undertook concept options (#5) for DIT and annotated the impacts and constraints of each prior to a preferred option being selected. The concept design skills and expertise demonstrated here is relevant for the HVSPP Intersection Upgrades project.
