A year behind schedule and millions of dollars over budget, an ambitious plan by regional officials to build a sophisticated network of bicycle lanes and pedestrian crossings has proven more complicated than first anticipated. Obstacles include everything from neighborhood outrage at the loss of parking spaces to the technical challenges of overhauling streets designed primarily for cars. The San Diego Association of Governments — the agency undertaking the now-$279 million project — has found itself in the crosshairs of frustrated groups on all sides of the issue, from business associations to homeowners to supporters of cycling.
