It's not as bad as it sounds, as the plan has been updated many times since 1978, with the last one in 2005 - the same year DC updated theirs.
The plan will focus on developing a high-quality / low-stress bicycle network, bringing bicycle recommendations in line with industry best practices, and consolidating all bicycle recommendations into a single plan for the first time since 1978. An emphasis will be placed on evaluating newer facilities, such as separated bike lanes, buffered bike lanes, and bicycle boulevards, as well as secure bicycle storage facilities. The planning process will provide ample opportunities for the community to get involved and offer feedback. Check out the Bicycle Planning web page to learn more.
On April 1, 2015 the Planning Department began working on a subset of the Bicycle Master Plan, focusing on the area surrounding Phase 1 of the planned Corridor Cities Transitway (CCT) to facilitate access from the surrounding communities to the future transit stations . This effort will ensure coordination and compatibility with the Corridor Cities Transitway, the Life Science Center Loop ( an off-road loop trail currently under design by the Planning Department), and development projects. The study area for this early effort is shown in the map below.
