I just realised that there exists a situation on the Pacific Highway where there is a bypass of a bypass.

The town of Nambucca Heads was first bypassed in 1980 (a two-lane limited-access road with at-grade intersections). Then in 2017 this bypass was itself bypassed by a motorway-standard road as part of the Warrell Creek to Nambucca Heads Pacific Highway upgrade.

Does anyone else know of a similar bypass-of-a-bypass (meta-bypass?) in Australia? I think they are reasonably common in North America (e.g. the Trans-Canada Highway through Fredericton, New Brunswick).

Cheers,
Brad

Would Peats Ridge Road (which bypassed Gosford for Newcastle-bound traffic) being bypassed by the F3 Mooney Mooney Bridge count?

Another example of a more recent bypass bypassed is Bangalow

The Pacific Highway has many examples of deviations around deviations with the current alignment being the third or fourth generation of the road

The Maitland bypass has been bypassed by the Hunter Expressway.

Also maybe not specifically what you had in mind, but weren't the Dunmore bends on the Princes Highway constructed to bypass Pioneer Drive? They've since been bypassed too.

What about Camden? The original bypass is Camden Bypass, which in turn is bypassed by the Hume Motorway.

As Lachlan said, there are quite a few on the Pacific Highway, e.g.

- Port Macquarie/Hastings River
- Telegraph Point
- Warrell Creek
- Macksville southward to Warrell Creek
- Swan Creek (to be bypassed by Woolgoolga-Ballina)
- Cowper (ditto)
- Maclean (ditto)
- Wardell (partial bypass of the 1960s deviation to bypass Burns Point Ferry)
- Newrybar
- Bangalow

I've only included the 60s-90s projects in that list, if you go back to the original 1928 alignment then there are many sections with 3 or 4 different alignments over the years.

Also Woolgoolga - the 1960s bypass of River St has been bypassed by the new A1

Nearly the entire current Bruce Highway between Bald Hills and Cooroy is a bypass of a bypass too. Much of the original two lane highway was rebuilt and realigned in the 50s/60s/70s, only to predominantly be bypassed by the current four lane highway.

Can't think of any others off the top of my head....

Could projects like the new M5 tunnel in Sydney be counted? Does the M5 qualify as a bypass of the Hume Highway?

Missed this earlier.

I think a Victorian entry would be the Calder at Elphinstone. The
original route would've been what's now Wright St., including the level
crossing over the Bendigo line. An overpass was built to remove the
crossing from the highway (remaining for local traffic) and bypass the
town. Although single carriageway, there were on and off ramps which
still appear on streetview, but have been removed and converted to
normal intersections from what I see on the overhead views (haven't been
out that way for ages). The section was marked as a freeway on some
older maps.
Of course this bypass has since been bypassed by the M79.

Darren.

This is a great example - one of Victoria's infamous single carriageway freeways.

I missed this question last month...

The Gawler bypass just out of the Adelaide metro area is the second alignment that I know of, or third of you count the Northern Expressway. The 1960s Gawler bypass was one lane each way, It's alignment was apporximately what is now the southbound off-ramp at Two Wells Road, then Two Wells Road/Winckel Bridge/Jack Cooper Drive/Hind Court/BreretonRoad back on to the current Main North Road Gawler Bypass, ending as the terminating road of a Tee-junction where the Adelaide Road came out of Gawler. My wife grew up where she could see the road a couple of kilometres from that junction and recalls watching the queue of traffic at the end of long weekends waiting to get through the junction.

The grade separations at Redbanks Road and Horrocks Highway were added as part of the second bypass, I think. Horrocks might have also been upgraded as the Sturd Highway dual carriageway was extended. Construction of the Northern Expressway interchange moved the northbound carriageway between Two Wells Road and the railway bridge, too.

Has Geelong been mentioned? The original Moorabool St/High St route was bypassed by the ring road


In Geraldton, the original alignment of the Mt Magnet Rd was via Eastward Rd/Johnston St/Eastern Rd/Bayly St; Utakarra Road was built in the late 1960s as part of the bypass to the Port (now John Willcock Link/NWCH) and then bypassed by the Geraldton Southern Transport Corridor Stage 2 project in 2009. A section of John Wilcock Link (then called Portway) was also bypassed on the approach to the Port as part of Stage 1.

Hi Brad, 

Here are the ones that come to mind:
  • Mandurah Bypass bypassed by Forrest Hwy
  • Bunbury Bypass (Robertson Dr / Forrest Hwy), surpassed by a heavy vehicle detour, which will eventually become a bypass of the bypass
  • Princes Hwy, Kembla Grange to Dapto. The route bypassed the old highway over Mullet Creek in the early 70s near the golf course, and was superseded by Southern Fwy.
  • Princes Hwy, Mt Brown. A bypass was made in the early to mid 20th century around Mt Brown, and then it was superseded in the late 80s when the the Southern Fwy was extended.

I don't know if this fits your criteria, but...

The Wells Road Bypass in Frankston was built in the 1960s, which would later become a section of the Frankston Freeway in the early 1980s.

In 2013 the Frankston Freeway was bypassed by the Frankston Bypass, AKA Peninsula Link.

Reopening this thread for a good cause. With the opening of the Wilman Wadani Hwy in Bunbury,  it seems that is bypasses 2 bypasses. Robertson Dr is the Inner Bunbury Bypass and the last 10 or so kms of the Forrest Hwy was originally the Australind Bypass
