Famous as the "best way to enter an American city," motorists travelling from the West on I-279 are given no visual cues regarding their nearness to downtown Pittsburgh as they enter the Fort Pitt Tunnels. Emerging from the portal, the Golden Triangle suddenly bursts into view framed by the yellow crossbracing of the bridge's arch.
