A 44 tonne gross vehicle weight restriction applies on the bridge with HGVs being limited to the inside lane on both sides of the highway.
With this in mind, each end of the Varioguard temporary barrier positioned on the bridge decking requires securing to provide stability to the barrier’s length, without bolting it to the deck! Concrete TVCBs are designed to deflect errant vehicles whilst providing a solid, stable end section. Tapered 3 metre long end sections lead into the Highways England approved ASSET barrier joints whilst oblong concrete sections provide runout on the steel barrier sections.
Laing O’Rourke’s Project Engineer for the Severn Crossing has high praise for the products and companies involved in keeping the 50 year old bridge “fit for purpose”.
Laing O’Rourke advises that they have had good service and good professional support with the temporary barriers being moved quickly and efficiently. This has helped tremendously when staff are working at height, with live traffic flow above water and at night.
