The road is expected to be re-opened to the public once line marking works have been completed.
The $600,000 project, funded through the Federal Government’s Roads to Recovery program, consists of two phases.
The street is prone to flash flooding and these works were designed to improve safety for residents, homeowners and visitors.
The first phase, which was completed on August 7, included works to rehabilitate road pavement, upgrade the kerb, improve the gutter system for homes, upgrade footpaths and improve drainage on the street during heavy rainfall.
The first phase was delayed because of wet weather conditions.
The next phase will consist of the same works to the north-bound lane and Mitchell Shire Council has allocated $635,000 in the 2019-2020 budget for this. Work is expected to begin by the end of the year.
Mitchell Shire Mayor Bill Chisholm said roads and footpaths were a priority for the council.
“We will be investing more than ever before in this infrastructure to ensure we prepare for our rapid population growth,” he said.
“Oak St is a very busy part of Seymour so I would like to thank the Australian Government for helping us deliver this project. The new drainage system will mean people and homes are safer.”
