Hwy 280 gets the utilitarian gold medal for use in San Francisco. This is due in no small part to its size, speed and excellent new construction. A problem with 280 is difficulty of navigating to intended streets from its complex exits. It is therefore more important here to use a map. The interchange with Alemany Blvd and Brotherhood Wy is especially confusing, making it a poor way to access Lake Merced. Greatest probability of heavy traffic is southbound between downtown and Hwy 101. The only park accessed directly is Balboa Park. Hwy 280 is an excellent way to access Hwy 1 to the coast of San Mateo county. Exits are significantly different in opposing directions.
