Balfour Beatty Mott MacDonald Revolutionary SAB Gate installed on motorway

Balfour Beatty Mott MacDonald (BBMM), working in partnership with the Highways Agency, is pleased to announce the first installation of SAB Gates on the Highways Agency network.

The SAB Gate provided by Highway Care is a modular ‘gate’ system that opens up the central reserve barrier on a dual-carriageway or motorway in just five minutes, to enable emergency vehicles to cross over, or traffic to be diverted in case of accidents or similar occurrences.

The gate consists of two anchor points which are connected to an adjacent barrier, with modular units that are 4,340mm long, 500mm wide and 1,100mm high. Each unit is fixed into position with cylindrical posts, which are placed into a socketed cored foundation and connected to a winch. When used, the posts are winched out of the foundation and the wheels are lowered down, allowing the barrier to be removed either in individual sections, as a whole unit, or to remain hinged at one end.

BBMM is in the process of replacing existing central reserve steel safety barriers with concrete step barriers at sites on the M4 and M5, which necessitates the provision of emergency crossing points.

BBMM Commission Manager, Anne Roberts said ‘Balfour Beatty Mott MacDonald, working in partnership with the Highways Agency, is proud to have been instrumental in the first use of SAB Gates in the UK.’

Compared to the previous systems used to provide ECP the SAB Gate is a more practical and user friendly product.
