The redevelopment is part of the $6 million Civic Cycle Loop project, a bicycle path that will circle the city centre and connect to other paths leading into Civic.

Three urban design consultants contracted by the ACT Government provided plans for the popular shopping strip, one proposing a 10km/hour ''shared zone'' with minimal signage or line markings, where all road users including motorists and cyclists would navigate the area at a slow speed, avoiding any crashes with one another.

The McGregor Coxall design also includes additional bicycle parking, seating, feature lighting and thermoplastic pavement stencils.

Stage Two of the plan would see the road raised to the the same level as the footpath.

A plan by consultants Tract would see a 30km/hour speed limit enforced on Bunda Street, with speed limits also reduced along Genge Street, Scotts Crossing, Petrie Street and Akuna Street.

Intersections would be shared by road users and paved with a different material to other sections of the streetscape, with roads in those areas raised to the same level as the footpaths. New bicycle racks, seating, bins and light poles would be installed, and the plan also includes street art, new trees, and four extra parking spaces. A Spackman, Mossop and Michaels proposal would see a distinct, two directional bicycle path on the southern side of Bunda Street, and would make the road one-way, south bound for motorists, who would access it at four separate left-in, left-out points.

The design includes the potential Bike Hub, which would sit at City Walk and may include bicycle storage, lockers and showers.

The design also features ''shared zone'' intersections that would enable cyclists to turn onto other cycling routes, and would be paved in a different material to remind road users of changed conditions.

The three designs will be on display in the Canberra Centre, on the upper level opposite Big W, until 30 January, then in the Civic Library until 7 February.

Minister for Territory and Municipal Services Shane Rattenbury said he would be consulting with interest groups including cyclist groups and Bunda Street traders during the coming weeks.

''We're not going in with any pre-conceived ideas, we're very keen to have the community give input right now and I'll be quite fascinated to see the preferred option that comes back from the various user groups,'' he said.

Mr Rattenbury had not seen specific costings for all the designs, but the entire loop had a budget of $6 million, and the government would weigh up feedback from the public and which features were likely to work best before making a final decision.
