Recent wet weather has delayed the next round of work on the paths on the Swan Street Bridge.
The south side will be closed until tomorrow and the north side from 20 August to 24 August.
Meanwhile, the Main Yarra Trail on the city side of the river remains closed at the underpass while investigations continue into improving the current awkward and narrow alignment.
The modifications will address some of the issues that emerged for people who ride bikes in the wake of the project to widen the Swan Street Bridge.
Victoria's Major Road Projects Authority announced that they will widen the area next to the bridge retaining wall on the eastern side of the Yarra River as well as change some line markings.
The changes will modify the alignment and marking of the approaches to address the pinch points and sight lines.
Bicycle Network held on-site discussions with VicRoads and the contractors to review the issues that are resulting in a negative experience for riders.
While the work is undertaken on these minor changes, some sections of the eastern Main Yarra Trail will be closed until the end of the month.
The western Main Yarra Trail is now open and has been raised to mitigate the risk of flooding.
The two new shared user paths over the Swan Street Bridge are also now open to bike riders.
Bicycle Network would like to thank everyone who reached out and gave feedback calling for change to the underpass.
