    Forest Road intersection upgrades: safety and capacity notes for designers

    Forest Road intersection upgrades: safety and capacity notes for designers

    First reported on Roads & Infrastructure (AU)

    30 Second Briefing

    Works will soon begin on the Forest Road Intersection Upgrades in Trevallyn, targeting a key junction on the recently duplicated West Tamar Highway in northern Tasmania. The works form part of a broader program of targeted intersection and access improvements along the highway, which now carries dual carriageway traffic through several sections. For designers and contractors, the project signals continued investment in localised safety treatments and congestion reduction at nodes rather than major new greenfield corridors.

    Technical Brief

    • Works form part of a programmed package of multiple, small intersection safety contracts along the corridor.

    Our Take

    Tasmania features far less frequently than east‑coast urban centres in our 936‑story Infrastructure category, so the Forest Road Intersection Upgrades project signals incremental safety‑driven spend in a state that usually appears only around major highway or bridge works.

    Roads & Infrastructure Magazine has been emphasising people‑centred outcomes in its ‘Roads Review: Looking Forward’ coverage, and this type of targeted West Tamar Highway intersection upgrade aligns with that shift from mega‑projects towards smaller, high‑impact safety schemes.

    Strabag’s Pfaffensteig Tunnel contract: design and delivery notes for rail engineers

    Strabag and Group company Züblin have secured the design-and-build structural works for the ABS Gäubahn Nord/Pfaffensteig Tunnel in south-west Germany, centred on an 11km twin-bore rail tunnel linking Stuttgart Airport station directly to the Gäubahn line towards Switzerland. About 9.8km will be driven by two TBMs, with conventional tunnelling for the A8 motorway undercrossing and airport connection, plus a 240m cut-and-cover section, retaining structures, railway underpasses and a grade-separated crossing. A 3km surface section will be upgraded and partially realigned for 200km/h operation, delivered under an integrated project delivery model with Ed. Züblin, Wayss & Freytag and Strabag AG sharing tunnelling, structural and earthworks packages.

    National Grid TBM under the Thames: tunnelling design and risk notes for engineers

    A 271.5‑tonne Herrenknecht Mixshield TBM, Caroline, has started driving a 2.2km electricity cable tunnel with a 4m internal diameter beneath the River Thames in Essex for National Grid’s Grain to Tilbury project, delivered by the Ferrovial BEMO joint venture. The drive will pass through variable Thames estuary ground conditions between 35m‑deep launch and reception shafts of 15m and 12m diameter, with tunnelling continuing into 2026 and overall scheme completion targeted for 2029. The new tunnel will replace the 1969 Thames Cable Tunnel and carry new high‑voltage circuits between Grain and Tilbury substations.

    Panama Canal Mixshield undercrossing: design and tunnelling lessons for engineers

    A 13.46m diameter Herrenknecht Mixshield TBM has broken through into the future Balboa station on Panama Metro Line 3 after completing the first-ever TBM undercrossing of the Panama Canal at depths exceeding 60m below sea level. The 5,600kW, 26,616kNm machine, fitted with an accessible cutterhead and more than 4,500 sensors linked via the Herrenknecht.Connected platform, has achieved peak advance of 150 segment rings (about 300m) per month through mixed sandstone, tuff, breccias and basalt. Around 1.5km of the 4.5km twin-track tunnel remains to final breakthrough.
