Springvale Junction, better known as Spaghetti Junction, is a particularly notorious road intersection in Melbourne. It is situated on the boundary of the suburbs of Mulgrave and Springvale.

[edit] Intersection

Springvale junction forms the intersection of four major roads, two of which terminate:

Springvale Road (route 40): along with Stud Road eight kilometres to the east, Springvale Road is the busiest north-south thoroughfare in the eastern suburbs, with speed limits of 70kmh and 80kmh, and a six-lane dual carriageway.
Princes Highway (route Alt 1): along with the Monash Freeway, the major thoroughfare from the south-eastern suburbs into the city, running northwest-southeast. Like Springvale road, a six-lane dual carriageway.
Police Rd/Centre Rd (route 16): two-lane single carriageway running east-west. These roads are slightly off-set from the main intersection.

Each of the six main corners of the intersection has shops or shopping centres on it.

[edit] Problems

Springvale Junction is notorious for three reasons:

It is extremely slow during peak times. The combination of outbound traffic on Princes Highway, outbound traffic from Centre Road, and traffic going both directions on Springvale Road means that traffic jams are frequent, and waiting times on Princes Highway in particular are fifteen minutes or more.
It is particularly confusing. With Police/Centre Rds slightly offset from the other two, Springvale Junction acts as three separate sets of traffic lights, with each road requiring two sets of right-turn lanes. In particular, south-bound Springvale Road traffic turning right into Princes Highway use the right-hand lane and turn on a right arrow; those turning right into Centre Road use the second lane from the right, advance on a green light, rather than a right arrow, and wait for a green arrow at the mid-intersection waiting point.
It is by far the worst blackspot intersection in Melbourne[1]. With the improvements to St Kilda Junction and Flemington Junction, Springvale Junction now has the most accidents of any intersection in Melbourne.

[edit] Improvements

The shopping centres make upgrades to Springvale Junction impossible. However, alternative thoroughfares are constantly built to ease the congestion:

The Monash Freeway takes much of the city traffic off Princes Highway.
The upgrade of Westall Road directs south-bound traffic from the west around Springvale Junction, and the slowest part of Springvale Road.
EastLink, when completed, should take traffic off Springvale Road.
The proposed Dingley Freeway, which connects with the existing Westall Road Extension would attract Dandenong traffic away from the junction.
