Bridge beams installed over Tonkin Highway
The Gateway WA team’s installation of the majority of bridge beams for the future Tonkin Highway / Horrie Miller Drive / Kewdale Road interchange has resulted in next weekend’s scheduled closure of a section of Tonkin Highway to be shortened to Friday night (24 October) starting at 7pm and finishing at 9am on Saturday morning (25 October).
To ensure the safe execution of the bridge beam lift, a section of Tonkin Highway was closed to the public last weekend as the bridge beams needed to be installed over the top of Tonkin Highway to rest on newly constructed bridge abutments.
A team of 50 Gateway WA personnel worked around the clock from Friday evening to install bridge beams and ensure Tonkin Highway was open on time for Monday morning commuters.
Challenging weather conditions threatened to postpone last weekend’s activities but the team was able to undertake the work safely and install the majority of bridge beams.
Large platform vehicles, known as self-propelled modular transporters, were used to move the beams weighing up to 103 tonnes from storage to their pick-up location. Two crawler cranes carried out dual lifts to place the beams into position.
A height restriction of 5.6 metres is now in place for all vehicles travelling on Tonkin Highway between Leach Highway and Kewdale Road / Horrie Miller Drive.
The previously advertised second closure of a section of Tonkin Highway for this upcoming weekend now only applies to Friday night to allow the team to undertake finishing work for the beams. This section of Tonkin Highway will reopen to the public at 9am on Saturday morning.
These activities have brought the future Tonkin Highway / Horrie Miller Drive / Kewdale Road interchange a step closer and the team will continue to move swiftly ahead with construction of the interchange.
When finished, the bridge will carry future traffic on Kewdale Road and Horrie Miller Drive over the top of Tonkin Highway, allowing uninterrupted movement.
