Technically, the function of the new Highland Bridge is to connect the Commons Park area with the Highland neighborhood. And its form -- 320 foot-long, triple-rib beams arcing 70 feet over I-25 -- is designed as another display of downtown's emerging architectural beauty. But for skateboarders, the bridge is simply a kick-ass new spot. The concrete banks that anchor the bridge's pylons serve as natural ramps for all manner of flip tricks, and the plaza beneath the eastern base of the arch has ledges and manual pads that encourage creative skateboarding experiments that must be executed around cyclists and stroller-pushing yuppies. That's what we call bridging the gap.
