Ashburton District TMP and CAR Support

Submitica CAR, TMP and WAP pathway

Ashburton District Council says CAR applications are made through Submitica, supporting documents should be uploaded there and a TMP may be required as part of the CAR. The local operating procedures say all TMPs must be submitted through Submitica and the assigned corridor manager will process the application or ask for more information.

Risk-based TMP expectations

ADC says a TMP is typically required when an activity alters normal operating conditions on a carriageway, footpath or shoulder, or outside the road corridor if road operation is affected. TMPs should align with NZGTTM, and older or template-based CoPTTM TMPs may need more detail.

Large rural and freight network

Ashburton District Council lists 2,617km of roads, including 1,515km sealed roads, 1,102km unsealed roads, 186 bridges, 233km of footpaths, more than 9,000 signs and more than 2,800 streetlights.

State highway, rail and second bridge interfaces

Ashburton straddles SH1 and the South Island Main Trunk railway, while NZTA says the Second Ashburton Bridge will connect Chalmers Avenue to Carters Terrace and a new road to Grahams Road, supporting Tinwald and Lake Hood growth.

Road closures, notification and event pressure

ADC road closure pages show current closures for water, fibre, infrastructure, second bridge work and events. The local procedures require public notification for affected facilities, residents or businesses, with specific lead times for parking, bus stops, road closures and one-way systems.

Ashburton CBD, Wills Street, Event Centre, library, museum and farmers market

Ashburton CBD works can overlap the Wills Street Event Centre, Ashburton Library, Art Gallery and Museum, East/Cass/Wills Street event closures, West and Havelock Street farmers market activity and central parking demand.

TMP note: Check event centre bookings, library/museum events, farmers market times, Wills Street closures, parking restrictions, pedestrian routes, loading, accessible parking and business/resident notifications before confirming work hours.

Tinwald, SH1, Lake Hood and Second Ashburton Bridge approaches

NZTA and Council material show Tinwald carries SH1 traffic, local access to Lake Hood, side-road intersections and the Second Ashburton Bridge route between Chalmers Avenue, Carters Terrace and Grahams Road.

TMP note: Check whether the work is ADC or NZTA responsibility, whether SH1 access from side streets is affected, and whether Lake Hood, Tinwald school, local businesses, bridge works or detours change the TMP assumptions.

Chalmers Avenue, South Street, Wilkins Road, Carters Terrace and Graham Street

Current ADC closure pages show long-duration closures around Chalmers Avenue, South Street and Wilkins Road for second bridge construction, plus Graham Street/Archibald Street and Jane Street works near SH1.

TMP note: Before nearby works, check the live closure map, local restrictions, bridge construction access, resident access, construction vehicles, detour routes and whether another active closure already occupies the work area.

Rural roads, irrigation routes, stock underpasses and forward works sites

ADC manages an extensive rural network and publishes forward works for rehabilitation, resealing, heavy maintenance, footpaths, kerb and channel, drainage and streetlights, while applications cover pipes under roads and stock underpasses.

TMP note: For rural work, check surface type, dust, farm and heavy vehicle access, irrigation timing, stock movement, approved contractors, road widths, detour distance, drainage works and whether the site appears in forward works or closure maps.

Ashburton Showgrounds, Brucefield Avenue and A&P Show

The Ashburton A&P Show is promoted as the largest two-day event in Mid Canterbury District and is held at Ashburton Showgrounds on Brucefield Avenue, with the 2026 show listed for 30-31 October.

TMP note: For work near the showgrounds, check show dates, set-up and pack-down, livestock and machinery movements, rural traffic, parking overflow, pedestrian crossings, side-road access and temporary event signage.

Lake Hood, EA Networks Centre and water/sport events

ADC lists the South Island Half Marathon at Lake Hood on 2 August 2026 and explains full or partial lake closures, while local event calendars show EA Networks Centre and school-holiday activity.

TMP note: Check Lake Hood access, lakeside roads, water-event restrictions, runner/walker routes, parking, emergency access, family drop-off, event set-up and whether the event needs TMP, Lake Hood or other approvals.

Methven, Rakaia, Mayfield, Hinds and Mid Canterbury visitor routes

Mid Canterbury event listings include district-wide visitor and community events, while ADC's rural network and SH77/Rakaia Gorge links can combine visitor traffic, freight, farming and weather exposure.

TMP note: Before work outside Ashburton township, check visitor-event dates, rural school routes, farm access, heavy vehicles, weather, SH77 or SH1 interfaces, long detours and whether ADC or NZTA needs to approve the work.
