The A82(T) Crianlarich Bypass proposals are broadly in accordance with the national, regional and local plan policies and guidance. Although the proposed scheme does not actively promote a modal shift to more sustainable modes of transport, the scheme would not lead to an increase in traffic on the road No significant potential for cumulative effects with other projects has been identified |
Mitigation has been defined for any potentially significant impact on the environment to ensure that any residual effects are reduced to the minimum for safe implementation of the development |
