The plans aim to create an environment downtown which resembles the bike-friendly portions of midtown, where cycling is popular and bikeways are more common.
This seems in line with what appears to be a growing trend of bike-friendliness throughout the region.
According to the article, the specific streets have already been allocated:
The first phase of the project will add painted bicycle lanes to J Street, I Street, 9th Street, 5th Street, 10th Street and Capitol Mall, where the roads are typically wide enough already to accommodate a dedicated cycle lane. In many cases, substantial bikeways can be added with little or no impact on existing traffic lanes or parking.The second phase will oversee the removal of existing traffic lanes from several major one-way streets. A single lane of traffic can be split to provide a dedicated cycle lane on each side of the road. Streets scheduled for the second phase of development include stretches of 5th Street, 9th Street, 10th Street, G Street and H Street.
