Built at a time when traffic in St. Tammany Parish was a fraction of what it is today, the U.S. 190 bridge at Claiborne Hill over the Bogue Falaya River is as busy as it is old. From its position just east of downtown Covington, the curving, two-lane overpass forms the neck of a funnel through which three lanes of northbound traffic from one of the north shore's busiest thoroughfares must pass en route to an area where more than 500 new apartment units and a major single family subdivision are in the works.
