    The roadway signs and the rounded shapes of the overpass bridges are consistent along the freeway and are part of the architecture.

    More recently the freeway is showing it's age. Years of traffic have taken their toll as well as the unsteady ground found in the valley which also contains the boundary between the pacific and north American plates. What was once a smooth strip of concrete now has bumps and dips in some locations. Another feature of the freeway is a separate drainage system to take the run-off water from the contaminated roadway away from the adjacent Crystal Springs reservoir which is part of the local drinking water supply. Environmental ahead of its time.

    Highway 280 and 680 on opposite sides of the bay were built as an east west pair. Instead of traditional simple cut and fill grading the hills are sculpted and rounded like the distant hills and are blended with trees and rocks to look natural. Hence this image. In essence the freeway is an architectural design blended with the landscape. It is a beautiful way to enter San Francisco from the south. You drive through green, forested hills as you approach a city of 800,000 people. The highway is designed for an 70 or 80 mile per hour cruising speed but soon after completion the speed was reduced to 55 because of the energy crisis on the late 1970s. The Stanford Linear Accelerator was built first and to avoid disrupting the ground around the accelerator the 280 bridge over the accelerator was built before the freeway was finished. For a time a bridge to nowhere. en.wikipedia.org/wiki/Interstate_2 80_ Will open in a new tab or window(California)
