Freight Access Bridge Program 2020

The Tasmanian Government is committed to strengthening Tasmanian bridges on key routes to retain the existing levels of service for heavy vehicle freight and community access. The Freight Access Bridge Upgrades Program upgrades state road bridges in order to allow for high-productivity freight vehicles (HPFV).

Seven bridges were strengthened in the first half of 2019 program, with a further six due to be upgraded in 2020.

To keep workers and road users safe, changed traffic conditions and speed restrictions will be in place during the works. Please follow all signs and allow enough time for travelling through work areas.

2020 Bridge Strengthening Locations

Bridport Road, Pipers Brook bridge, Pipers Brook

Works will start 4 May and are expected to be completed by 12 June, weather permitting.

Traffic impacts

Works will take place from 7:00 am – 6:00 pm.

During our working hours, the speed on Bridport Road will be progressively reduced to 40km/h in both directions over a distance of about 600 metres leading into the bridge.

After hours the speed limit will be 80 km/h.

There will be some single lane closures during the works, but one lane will remain open at all times, except during some short term traffic stops required in the final week of the works.

Pipers Brook bridge

Bridport Road, Little Forest River bridge, Bridport

Works started in March, but have been postponed.  Works are expected to be completed in June, weather permitting.

The strengthening involves fixing carbon fibre systems to the underside of the bridge, and concrete works on the piers.

During the carbon fibre and pier strengthening works we will need to reduce the speed limits to minimise vibration on the bridge.

Traffic impacts

Works will take place between 7:00 am – 5:30 pm.

During working hours, the speed limit on Bridport Road will be progressively reduced to 40km/h in both directions, over a distance of about 600 metres leading up to the bridge.

The speed limit will be temporarily reduced to 20 km/hr during and after working hours, for a short period during the works. More information will be provided closer to the start date.

Little Forest River bridge

Brooker Highway, Humphreys Rivulet bridge, Glenorchy

Works will start 17 March and are expected to be completed by 19 May with impacts to traffic beginning 3 April, weather permitting.

The strengthening involves fixing carbon fibre systems to the underside of bridges.

While the carbon fibre is being installed we will need to reduce the speed limits to minimise vibration on the bridge.

Temporary speed humps will be installed to slow traffic to make sure that vibrations on bridge are minimised.

Traffic impacts

Works will take place between 7:00 am – 5:30 pm. Traffic delays are expected to be under 8 minutes.

During working hours, speed on the Brooker Highway will be progressively reduced to 40km/h in both directions, over a distance of about 160 metres leading  up to the bridge.

The speed limit will be reduced to 40 km/h after hours during the carbon fibre curing period, between 3 April and 19 May.

All lanes will remain open at all times.

Humphreys Rivulet

Brooker Highway, Berriedale bridge, Berriedale

Works will start 27 May and are expected to be completed by 18 June, weather permitting.

Traffic impacts

Our usual working hours will be 7:00 am – 5:30 pm.

Night works will take place between 7:00 pm – 6:00 am, from 4-15 June.

Traffic delays are expected to be under 8 minutes.

Traffic will be reduced to 60km/h in both directions at all times, over a distance of about 170 metres leading up to the bridge.

Access will be maintained to the on and off ramps near the Berriedale rail underpass at all times.

The northbound shoulder of the Brooker Highway will be closed, with outside lanes closed in both directions during night works from 4 June to 15 June while the strengthening materials are installed.

The cycle path will remain open to pedestrian and cyclists at all times.

North West Bay River brige

Huon Highway, Leslie Road bridge, Leslie Vale

Works will start 3 April and are expected to be completed by 8 June, weather permitting.

Traffic impacts

Works will take place between 7:00 am – 5:30 pm.

Traffic delays are expected to be up to 8 minutes, based on normal traffic conditions.

Speed on the Huon Highway will be progressively reduced to 40 km/h in both directions, over a distance of about 600 metres leading up to the bridge.

Reduced speeds will be maintained after hours until the road surface is re-instated.

From 8 April – 22 May traffic will be reduced to one lane in each direction, and temporary barriers will be installed that will reduce the lanes to 3 metres wide. 8

Leslie Road will be closed at the underpass during working hours. Local traffic will be able to access Leslie Road underpass after hours and during weekend. Detours will be available via Summerleas Road and the Huon Highway. Download detour maps here.
