Highway Bridges

Box culverts are an ideal solution for instant bridging. Humes precast concrete box culverts suit difficult site conditions as installation requires minimal excavation and backfill. They are designed to tolerate heavy wheel loads even with no or minimal overfill in place.

Humes manufactures a full range of box culverts (from 300mm to 6,600mm span) and configurations to Australian Standards AS 1597 (parts one and two). Box culverts are generally available in standard lengths of 1.2m and 2.4m but can be manufactured in custom designs such as splayed units.

Humes manufactures a wide range of prestressed bridge componentry including girders, decks, planks, I-beams and hexagonal prestressed piles. These prestressed items are suitable for major bridge infrastructure, with Humes’ in-house engineering team able to design non-standard solutions. Humes is an accredited manufacturer of prestressed structures for road and rail authorities, supplying decks and planks (up to 25m), Super-T girders/T-Roffs (up to 35m) and I-beams. Cathodic protection systems can be encased, particularly in tidal splash zones, to ensure long service life.

Humes stormwater pipes and headwalls provide an ideal solution for highway crossings over waterways where minimal backfill is required. Steel reinforced concrete pipes are available from DN225 to DN3600 in standard strength classes 2–4 and super strength classes 6–10.
