Planning has commenced for an extension of Camden Valley Way

[Henry]

Hi all,

https://www.nsw.gov.au/ministerial-releases/camden-bypass-extension-planned

Planning for the northerly extension of Camden Bypass to meet Camden Valley Way has commenced.

It appears to be an overpass at most likely Narellan Rd.

I would like to see it grade-separated when it connects with Camden Valley Way bypassing the current intersection with Smeaton Grange Rd.

Thanks,

Henry

Camden Bypass was always designed to connect with Camden Valley Way (which was the original Hume Highway) but was never constructed and I think pre-dates the final F5 design alignment. The partial interchange at Narellan Road was put in as an interim connection for Hume Hwy traffic to/from Camden Bypass when Narellan Road carried Hume Highway traffic between 1974 and 1980 and before the Campbelltown-Yanderra section of the F5 was completed.

Always seemed like a no-brainer that I’m surprised they never built. The reserve is there, and the huge ramp onto Narellan Road clearly accommodates it.

I'm quite surprised they didn't leave it in the initial at-grade intersection setup from when the bypass first opened, especially if there were plans to extend the F5 at that stage. Was there a reason they added the overpass afterwards?

Here are some interesting aerial images from 1977 that show the Camden Bypass ramp and the F5 south of Narellan Rd both under construction at the same time:

woah, that TIFF is 750MB. You can see lane markings on it.

The at-grade intersection was always only a temporary arrangement relating to the staging of the project and staging of funding. The bridges over Narellan Road were always intended to be built but the decision was made in early 1975 to omit the connections to/from Camden Valley Way and only build the ramp connecting to Narellan Road. Accordingly the southbound bridge was omitted and the northbound bridge was built to a much reduced width, suitable for the off-ramp only. 

At this time the F5 had just been completed to Narellan Road so there was a significant increase in traffic coming off the Camden Bypass and turning right towards Campbelltown, rather than left towards the existing highway. This probably warranted the building of the ramp to Narellan Road rather than the long term retention of the at-grade intersection. 

IIRC the bridge and ramp to Narellan Road were completed in 1977, at which stage the extension of the F5 from Narellan Road to Yanderra was still over 3 years from opening. 

A DMR plan showing the planned interchange layout below. A simplified version of this appeared in UBD street directories for a number of years as a constructed road!

I will be interested to see what TfNSW come up with for in the current planning work. The intersection with Camden Valley Way will almost certainly be a set of signals - surely?
