In case you missed it earlier, a woman has been killed in an alleged hit-run in Melbourne's west. The woman was fatally struck on Ballarat Road in Ardeer. Her body was found just before 8pm last night.

A 31-year-old Cairnlea man handed himself in to police this morning and is currently assisting with inquiries. The victim is yet to be identified.

The westbound lane of Ballarat Road is closed between the Western Ring Road and Hulett Street. Police have asked motorists to avoid the area.

Here's how it looks at Ardeer this morning, thanks to 3AW reporter Pat Mitchell.

It's normally an essential part of tram travel. Not this morning. Put your phones away and bring a book for the wait. Yarra Trams has just released this warning to commuters:

The answer for yesterday was HYPOCRITE. 

The Andrews Labor government has put the brakes on big new spending and building initiatives in its fifth budget as it begins the task of keeping its campaign promises and paying for the huge policy agenda it took to last year’s election.

Senior economics correspondent Shane Wright calls it a budget built on tunnels, babies and migrants.

If you missed our coverage yesterday, here's the condensed version:

Only one lane is open to inbound traffic on Ballarat Road in Ardeer at the site of an alleged hit-run last night.

Inbound traffic is heavy and currently pushed back to the M80 Ring Road, according to a VicRoads spokesperson. Drivers are advised to consider alternatives, like taking the West Gate Freeway.

Meanwhile, the road remains closed for outbound traffic. Drivers who need to access the M80 could take Furlong or Boundary roads.

The Melbourne City Council area has about 40 green roofs, covering five hectares of space. This compares to Toronto in Canada which has about 500 green roofs and Munich, which has 300.

We're talking city conservation this morning, and new research to discover why Australian cities are lagging behind those in Europe and North America with green roofs, despite the environmental and social benefits.

Three people have died in two separate crashes overnight, bringing the state's road toll to 137 - 49 more than the same time last year.

The latest deaths were at Mount Eliza on the Mornington Peninsula, where two people were killed in a crash on the Nepean Highway about 11pm. The driver and passenger of the north-bound vehicle died at the scene. The male driver of the second vehicle was taken to hospital with non-life threatening injuries.

Earlier in Red Cliffs near Mildura, a car carrying three men in their 20s left the road and hit a pole. One of the passengers died at the scene. The other two men were taken to hospital.

A young woman bashed to death in a Melbourne park had been at a social gathering hours earlier with the man accused of killing her. Friends who had been at the gathering with 25-year-old Courtney Herron came forward and led detectives to the man now charged with her murder, The Age understands.
