Boundary St bridge Roseville news

 
  awsgc24 Minister for Railways

Location: Sydney
Work has started on renewing the Boundary Road underbridge between Chatswood and Roseville.

The height of this bridge at 4.2m is a bit low and causes truckstucks from time to time.

The bridge has only three lanes, one eastboound and two westbound, which is not enough giben close proximity to intersections at the Pacific Highway on the westside, and Archer Street on the eastside.

It is not yet clear how many lanes the new bridge will cover.

It is reported that the intersection with Hill Street (leading to Roseville) will be abolished as the lowered Boundary would have too steep a gradient.

The tracks will remain at the current level while the road will be lowered.

I used to live in Roseville. Sounds like a big pain to get into Roseville from Chatswood by car due to Hill Street and Boundary intersection closure.

One would have to go up to the Pacific and go around or turn right onto Boundary and turn left to go onto Victoria St
(assuming one was coming from Chatswood on Archer St)

So is the rail overpass staying the same or widened to be able to take 4 tracks?

I noticed a while ago they demolished the house that was on the corner with the Pacific Highway and Boundary st. The land seems to have sat idle. I am now curious as to whether this becomes another lane to turn into Boundary thus retaining the pacific highway as a 3 lane southbound road until Chatswood.

afaik, the railway land is 2 chains or 40 metres wide and would have room for 2 extra tracks, one each side of the new bridge.

Of course, there isn't room for two extra tracks the whole way from Chatswood station to Roseville.

OK, so you are suggesting that the bridge will be a 2 track replacement, not a bridge built with the ability to easily lay 4 tracks in the future for the old Chatswood to Gordon quad plan e.g. as done between St Leonards and Artarmon where the bridge was built to take 4 tracks but two were laid. However in the future you could add additions to the bridge either side to run 4 tracks.  

Obviously the 4 tracks for the Gordon quad would have to merge in to two where the ECRL tunnel surfaces. However all North Shore trains stop at Chatswood and even with 4 tracks southbound the lines shared with the ECRL so that shouldn't matter.

The other spot that would be an issue for the Gordon quad would be Lindfield but you could make it fit with a fair bit of work.

Thanks for that info Doc.

It certainly suggests that the bridge will be built straight up for and extra pair of tracks or even quadded lines.

Signalling and power cables appear to have been diverted to a beam that spans the future 6 lane Boundary Street.

The extra width is on the northern side.

A pamphlet from the local state MP, says that the new 4 track and 6 lane Boundary Road under-bridge cost $15m. The two outside spans are unused by rail, "just in case" they are needed.

Strictly speaking, the Boundary Road bridge is on the boundary between two state MPs, hence the road's name. Smile

What a waste providing for 4 tracks over Boundary Street for something that will never happen. The tunnel (RES) near Chatswood already has two rail tracks for the North shore and two tracks for the North West Rail link, no room for more tracks.

This money for the bridges at Boundary St would have been better spent commencing the Down relief that starts beyond West Ryde station with a new bridge over Victoria rd and points coming off after Meadowbank station.

The Victoria Ave bridge at West Ryde has only 4 lanes; if this were widened to six lanes, that would be the opportunity to get an extra track? SadSmile

I don't see land part of a 40m wide railway corridor alongside a working railway in Sydney being handed over to anyone anytime soon. A fence will need to be built hard to the tracks limiting access by track crews. I remember in the 80's the then SRA going through the main north and other areas developing parrellel service road access to the rails all over the place. Most of the North shore line has banked easements thus limiting that 40m to something much smaller.
