There are two major kinds of barriers to walking in the city, natural barriers such as the two rivers, and constructed barriers such as the freeways. Fixing either kind will be quite expensive. I am in favor of pedestrian and bicyclist bridges, perhaps with transit if appropriate, but not motor vehicles. Though a small increase in the number of road crossings is needed, most of these are outside the city in the county.

Policies:

• Construct safe pedestrian and bicyclist over-crossings of freeways, and rail lines without street-level crossings, at an interval of no less than one-quarter mile, to improve circulation. Work with Caltrans, railroads, and the legislature to ensure that the expense is shared and not the sole responsibility of city taxpayers. Complete within ten years. 
• Consider safe pedestrian and bicyclist crossings of the rivers (Sacramento and American) at an interval of no less than one-half mile, to improve circulation. Complete within 15 years.
