Council warns of impact on Brougham St suburbs

A $90 million upgrade of a busy Christchurch road could have a detrimental impact on the city’s oldest residential neighbourhoods, the city council warns.

Waka Kotahi NZ Transport Agency (NZTA) is proposing changes to Brougham St, including a pedestrian overbridge, building a third lane in place of parking spaces, and a shared cycle-pedestrian path.

The agency wants to have ‘‘T2 lanes’’ during peak hours – for buses, cars with at least one passenger, or motorcycles – but the Christchurch City Council wants them to extend beyond Brougham St all the way to Rolleston. Outside peak times, they would be available for parking.

In a submission to NZTA about the project, the council said the proposals did not adequately consider the impacts on adjoining suburbs. Brougham St bisects some of the oldest residential suburbs in the city, including Sydenham, Spreydon, Waltham and Addington.

The council said it was concerned that the proposals would increase noise, vibrations and emissions for residents, because the traffic would be closer to homes.

Part of the project’s success relies on the council making changes to surrounding roads, and the council called on NZTA to pay for those changes.

It said it did not want to see ratepayers burdened financially as a result of the project, and wanted to avoid a repeat of NZTA’s northern corridor project, for which the council had to spend millions of dollars adapting local roads.

Brougham St is classed as a state highway, so it is the responsibility of NZTA, but the roads leading into it are under the council’s control.

An average of 45,000 vehicles, including 4500 freight vehicles and trucks, use the road each day. It is a crucial link for vehicles carrying freight to and from Lyttelton Port.

Under the proposal, intersections will be upgraded, with more traffic signals, turn arrows and bus priority lights.

The pedestrian overbridge will connect Collins St and Simeon St, which under the plan would both become vehicle cul-de-sacs.

A shared cycle-pedestrian path would be separated from the westbound lane with new trees, between Simeon St and Opawa Rd. The council said the shared path might not be wide enough for pedestrians and cyclists to safely travel together, and wanted it to be made wider.

It was also concerned that the proposals did not provide for commuter cyclists, who were unlikely to use the shared path. The council wanted an assurance that there would be provision for on-road cycle lanes at least 1.8 metres wide.

However, Councillor Phil Mauger said at a council meeting yesterday commuter cyclists should be encouraged to ‘‘rat run’’ (take short cuts on side roads) down another road because there was not enough room for them on Brougham St.

Cr Melanie Coker was concerned that there was no provision for a right-hand turn into Selwyn St, but the council believed that this would lead to vehicles rat-running. She said the community had fought for years to get the turn put in.

She wanted NZTA to put the physical work on hold so it could address all the council’s submission points.

Public feedback on NZTA’s proposal closes today.
