Maroondah Highway safety improvements, Coldstream to Healesville

We’re improving safety along the Maroondah Highway, between Stringybark Creek in Coldstream and Healesville-Koo Wee Rup Road in Healesville, as we work towards a future where no one is seriously injured or killed on our roads.

Project Update - November 2020

Works to improve safety on the Maroondah Highway between Coldstream and Healesville are currently on hold. The extended season of cold and wet weather conditions has meant we can’t start back to completing the road surface. Dry ground and warmer temperatures are needed for our roads to set correctly. The team have been out recently to do a dry back test, which tells us the level of moisture still in the newly laid pavement. Testing started in early November and will continue until we get the results we need to return to work. 

Once intersection upgrade works are completed, we will finish installing flexible safety barriers, as well as install wide centrelines and rumble strips in high-risk areas of this stretch of the Maroondah Highway. 

What this means for you

While works are suspended, we’ll place temporary bollards to mark the boundaries of traffic lanes in both directions at works sites to ensure the safety of all road users. 

The new safer speed limit of 80km/h will be in place on the highway between Coldstream and Healesville.

By making sure the speed limit is right for the road conditions, we can help prevent crashes from happening, and reduce the severity when an accident is unavoidable. 

If you’re travelling through the area, keep an eye out for changed traffic conditions, plan-ahead and drive safely.

We thank you for your patience while we complete these important safety improvements.

Cycling on the Maroondah Highway

There are currently intermittent dedicated bicycle lanes along the Maroondah Highway between Coldstream and Healesville. 

While we work to deliver safety improvements along this stretch of the Highway, we’ve temporarily closed some existing bicycle lanes where impacted by works. This includes bicycle lanes at the intersections of Tarrawarra Road, Domain Chandon, Maddens Lane, and Maxwell Road.

These bicycle lanes will be reinstated when works are complete in late 2020.

What we’re doing

Since February 2020, we’ve been delivering road safety improvements on the Maroondah Highway. We’ve listened to the local community and we’re delivering intersection upgrades at four busy intersections along the highway to reduce the risk of rear end and side impact collisions which can lead to serious injury for all road users. 

We’re making the following changes to improve safety on the road:

  • Intersection improvements at Tarrawarra Road, Domain Chandon, Maddens Lane and Maxwell Road.
  • Left hand side barriers in high risk locations
  • Wide centre line treatment
  • Centreline rumble strips warn people when they start to veer from their lane; and
  • A safer speed of 80km/h between Coldstream and Healesville

By adding dedicated turn lanes, we’ll provide better separation between turning and through traffic and improved accessibility to many popular wineries and businesses in the Yarra Valley. 

A wide centreline, supported by rumble strips allows drivers more time to correct if they start to veer from their lane to the centre of the road, and reduce the possibility of head on crashes.

Flexible safety barriers are already in place along some sections of the road. We’re installing additional flexible safety barriers on the left-hand side to reduce the risk of run-off-road crashes.

Infrastructure plays a vital role in preventing serious crashes. It also helps reduce the severity of crashes when they’re unavoidable.

Road safety infrastructure such as flexible safety barriers, wide centreline treatments and rumble strips help prevent the most common crash types, head-on and run-off-road collisions, which in 2015 were responsible for 40% of Victoria’s road deaths and serious injuries.

Mistakes happen, which as humans we can’t always avoid. What we can do is build more forgiving road infrastructure so that when a mistake does happen on the road, it doesn’t cost a life.

Maroondah Highway is a popular tourist route in Victoria’s east, linking Melbourne and the growing outer suburbs to the famous Yarra Valley wine region. This stretch of the Maroondah Highway connects many well-known wineries as well as breweries, restaurants and local farmers markets. 

Between July 2013 and December 2018, there were 13 serious injuries along this stretch of road and tragically, three people lost their lives. Most of the serious injuries occurred as a result of head-on collisions, due to vehicles drifting onto the wrong side of the road.

Why a safer speed limit?

Speeding is a major factor in serious injury crashes.

Maroondah Highway is a high-risk, high volume road with increasing traffic volumes and tourist numbers visiting the popular Yarra Valley region. These visitors are often unfamiliar with the region and usually drive at a reduced speed.  

The new 80km/h speed limit adds less than two minutes travel time to your journey to and from Healesville. 

By implementing a safer speed limit of 80km/h, the stopping distance is 30% shorter than when travelling at 100km/h, reducing the risk of serious injury for all road users. 

Driving at 80km/h gives you 20% more time to react in dangerous situations and make better decisions than if you were travelling at 100km/h. 

To improve traffic flow and reduce queueing along the Highway, we’re also adding dedicated turning lanes at the four key intersections.

Driver skills and experience vary greatly from person to person, we’re safer when the speed matches the road conditions and surroundings.
