Quite a busy period for grade separations over the last ten years, certainly a higher rate per head of population than Victoria managed in the same time. I count at least 25, plus a couple which count partially.
Rail under rail: 2 (replacing Goodwood Junction and Torrens Junction flat crossings)
Rail under road: 8 (Goldsmith Dr, Old Honeypot Rd, Seaford Rd, Lynton Tce all on the Seaford Extension, Victoria St on the Goodwood Junction project, Park Tce and Gibson St on the Torrens Junction project, Morphett Rd on the Oaklands Crossing project)
Road over rail: 1.5, made up of 0.5 (Northern Expressway, counts for 0.5 as the project was started before this decade but opened in this decade!) and 1.0 (South Road Superway)
Rail over road: 1.1, made up of 1.0 (Torrens to Torrens bridge - but should it maybe count for more due to it crossing the North-South Motorway and South Road?) and 0.1 (Flinders Link, one of ten spans installed so far)
Rail over river: 2 new (Onkaparinga River bridge on the Seaford Line that also crosses River Road, additional Onkaparinga River bridge built alongside the existing one at ARTC's new Ambleside passing loop), 2 substantially rebuilt (Sturt River, Port River)
Pedestrian station access bridges: 8 opened (Elizabeth, Munno Para, Seaford, Seaford Meadows, Blackwood bridge over ARTC track only, Adelaide Showgrounds, Bowden, Oaklands), 2 closed (Marion, Keswick closed to public use with the bridge still partially intact for utilities)
Pedestrian station access underpasses: 1 opened (Marion), 1 closed (old Bowden)
Other footbridges: 2 new (Station Place bridge near the old Bowden station location, parklands footbridge halfway between Park Tce and the former Torrens Junction site)
Oaklands Station was demolished and rebuilt twice.
The first time was in the previous decade.
Both times, the new station was built before the old one was demolished. The same could not be said for Elizabeth, where the rebuild earlier this decade (old island platform removed, new prefab station with side platforms assembled) happened during a lengthy closure of the line.
- 30 minutes service frequencies commencing after hours on the Outer Harbor, Seaford, and Gawler Central lines.
- Belair stabling yard closed
Belair also gets 2 trains per hour in the evenings, and the stabling yard was reopened when service resumed at the end of the Goodwood Junction project, initially only used on weekends for a couple of months and then returned to nightly use..
The stabling sidings at Lonsdale, however, remain out of use.
