It came in response to a number of problems that altered the design scope and exhausted its contingency sum, causing its budget of $6.4 million to blowout.

Wagga councillor Paul Funnell said he was frustrated that the original design put forward had not used the historical knowledge available to the council.

However he said the current council staff guiding this project inherited "a dogs breakfast".

The councillors unanimously approved six scope changes and three variations, amounting to $505,311.

This included a culvert crossing, asbestos excavation and removal, cycle pathway, bus parking bays, a bridge over a water main, rock excavation and material cartage.

They were asked to support a request to fund the connection of two parts of Messenger Avenue, however this was denied.

The additional funds required, and approved by the council, were $251,569.
