C10 City to Molonglo Feasibility Study

The Molonglo Valley to City Trunk Cycleway: Feasibility Study was the result of the ACT Labor and ACT Greens 2012 Parliamentary Agreement: also known as the “C10 City – Molonglo” cycling route and an official CBR Cycle Route (Principal Community Route). It is intended to provide a direct and high-quality cycling route between the Molonglo Valley and the City.

The Molonglo Valley to City Trunk Cycleway: Feasibility Study is not on the ACT Governments website. Currently, it is not funded in any ACT Budget. The section through the suburbs of the Molonglo Valley development will be built along with the roads. The focus here is to finish the suburb and not to finish the route. The concept of building a cycle highway independent of roads is alien to the ACT Governments thinking.

Further, the corridors for active travel infrastructure are reserved through the Active Travel Infrastructure Practitioner Tool. The routes in this online tool should be considered for all urban developments. If a route is not planned it will never be built. The corridors for active travel are called Active Travel Route Alignments (ATRA). However, the C10 is not found in the Active Travel Infrastructure Practitioner Tool (figure 3). And many other Active Travel Route Alignments are out of date.

3.2 Active Travel Route Alignments

The current version of the Active Travel Routes (ATR) are available for use in preparing land development proposals at both a broad strategic scale and site specific level. The Active Travel Route Alignments (ATRA) represent an interconnected web of routes in established areas as well as indicative (future) alignments for routes in new areas. It is not intended to represent the facilities that currently exist on the routes, rather it shows the best alignments for human powered transport and recreation.

Traditionally, in the ACT routes for active travel modes such as walking and cycling were planned within “green corridors” utilised for “cycle paths” connecting main destinations. In recent times however, routes have followed roads with the level of amenity such as path width and lighting levels dictated by the road hierarchy. Open spaces have been subject to landscaping only, with little regard to “big picture” planning or the design of facilities necessary for active travel. This approach has not provided for route characteristics likely to encourage active travel as an alternative travel mode over vehicle use.

The Study

The Cycleway would consist of a 4 m wide asphalt path. At the edge of the path pavement the optimal arrangement will be to provide a 0.5 m shoulder and 0.5 m clear zone. The total potential cross section width of the corridor is 6 m (4 m path, 1 m shoulders, 1 m clear zone). The clear zone and shoulder widths may change based on constraints along the corridor.

Figure 5: Benefits identified for the Molonglo Valley to City Trunk Cycleway Project

The results of the cost-benefit analysis indicate that the development of the Molonglo Valley to the City Cycleway project is economically viable. The Cycleway presents a positive net present value (NPV) of $12.7 million and a BCR of 1.6. This means that the construction of the Cycleway would have an overall positive impact for the Canberra Community. The benefits associated with the completed infrastructure are greater than the cost of constructing and maintaining the Cycleway.
