Gateway Motorway flyover - strengthening works and heavy vehicle restrictions
We would like to advise that following a structural inspection of the Gateway Motorway flyover at Gympie Arterial Road, Bald Hills (see map below), it was identified that strengthening works were required on the flyover structure.
Since 1 September 2019, heavy vehicle restrictions have been in place, to ensure ongoing safety for all road users while further investigations and subsequent works are undertaken.
Enabling works have been completed and construction is now underway.
Changed traffic conditions will be in place while works are undertaken and some delays are expected.

This is the northbound flyover of the Gateway Motorway - where it merges with the
M1 at Bald Hills. Every weekday, over 40,000 vehicles use this section of road.
TMR recently imposed changed heavy vehicle restrictions here. Further travel
restrictions may also apply and special permits may be required.
Travel restrictions include: Oversize low loaders over 102.5t and
Platforms over 104.5t are prohibited from using the flyover.
Oversized Platforms with a Gross Combined Mass
between 59.5t and 104.5t must
straddle the centre line at no greater than 10 km/h and be accompanied by an
escort. For these vehicles, travel is only permitted between 8:00 p.m - 5:00am.
If you're operating a vehicle required to straddle the centre line at a
speed not exceeding 10 km/h, please contact the Brisbane Metropolitan
Transport Management Centre, prior to the Shell Service Station at Nudgee.
BMTMC will support your safe travel over the flyover, with speed limits displayed on
electronic and overhead variable message signage. Low loaders between 59.5t and
102.5t must straddle the centreline and be
accompanied by a pilot or escort. For these vehicles travel is only permitted
between 9am-4pm, Monday to Friday. Night time travel may only be
permitted if operating under a notice or permit, identifying specific travel times.
All other heavy vehicles must only travel in the left-hand lane.
Additional signage has been installed on the approach to the northbound flyover,
warning drivers of the restrictions and ensuring heavy vehicles can continue to
safely use this section of road. Thanks for your patience while we make our
roads safer for all Queenslanders. For more info visit tmr.qld.gov.au/gatewaymotorwayflyover
