Interstate 280 remains the finest freeway in the nation. However, there is a major problem that needs to be fixed. Southbound, just south of Palo Alto, the freeway scrunches from four lanes to three when the right lane becomes exit only. Then the fourth lane reappears, only to disappear again as an exit only. Then it reappears again and remains there until the 85 junction (and well beyond, though I almost never have reason to go beyond). So, why did they do this? In heavy-ish traffic, that loss of a lane always causes a massive back-up. Clearly, they could have made it four lanes straight through--there is room. These stupid bottle necks are a pain and unnecessary. Boo, Cal-Trans.
