Bridgeworks in full swing
by DAVID HOGG
18th May 2018
AFTER A two-month delay from the original scheduled weekend closure, the Warrandyte Bridge was fully closed over the weekend of May 5–6 and works have now resumed in earnest on the main bridge structure.
Single lane working occurred on April 18 for the AusNet works to replace the power pole at the bridge, and then again on May 2 for the VicRoads bridgeworks.
Although conducted outside the peak period, these single-lane working days caused significant traffic congestion in all four directions, the worst being on Ringwood-Warrandyte Road. Traffic delays ranged from 15 minutes to 40 minutes, with the average wait time being around 22 minutes.
VicRoads told the Diary that all future single lane closures will be done at night to minimise the impact on the community.
The installation of the protruding cantilever beams was completed during the period of single-lane working on May 2, and the big job of completing installation of the three huge lateral beams was performed very efficiently during the weekend of May 5–6.
In fact, the job was done so quickly that the bridge was reopened to traffic late on May 6.
The result of this work is that there is now a long lateral beam running for the entire length of the bridge about three metres out from original structure on the downstream side.
The job over the next few weeks will be for massive concrete pours to fill in the gap, following which we will have a much wider bridge surface. The existing railings on the downstream side can then be demolished and a new barrier erected to separate the new northbound lane from the new shared walkway.
At the same time, work is continuing on the north side to erect new traffic barriers, and on the upstream side in preparation for a slight overhang to accommodate the new pedestrian pathway on that side.
Although the May Information Update Bulletin has removed reference to the expected completion date, engineers advise they are still hopeful that the work can be completed by September/October.
Further full weekend closures are expected in the next couple of months, but at this stage the dates for these have not been set.
Rat-runners prompt temporary road closure
By DAVID HOGG
NILLUMBIK Council advises that following consultation with residents it has resolved to implement a temporary road closure on Dingley Dell Road near the intersection with Blooms Road while the Warrandyte Bridge upgrade works are in progress.
Residents have been vocal in their disgust of “rat-runners” speeding down the narrow dirt road to avoid the traffic build-up on Research-Warrandyte and Kangaroo Ground-Warrandyte Roads.
The temporary road closure will be in the form of a gate and is scheduled for installation mid-May.
The gate will be removed and the road reopened once the bridgeworks have been completed.
Complimentary signage to reinforce the road closure will also be installed on Kangaroo Ground-Warrandyte, Research-Warrandyte and Blooms Roads.
Signage is also proposed at the southern leg of Dingley Dell Road to advise of the road closure ahead to enable vehicles to turn at Dingley Close.
Nillumbik Council recognises that the road closure is likely to result in an inconvenience to the broader community; however, it considers this intervention critical to manage the unprecedented ‘cut-through’ traffic use of this local road.
