A distraught man ventured to the edge of an elevated stretch of Interstate 5 near Mission Valley Wednesday and remained perched there for nearly three hours before surrendering, forcing a northbound freeway closure that snarled traffic for miles during the lead-up to the Fourth of July weekend.

The unidentified pedestrian appeared at the eastern side of the regional freeway just south of Interstate 8 about 10 a.m., according to the California Highway Patrol.

Authorities shut down the entire northbound side of I-5 in the area while police tried to talk the man off the bridge. Soon, vehicles were at a standstill for miles to the south. the CHP reported.

As the standoff continued through the late morning, the CHP began diverting northbound traffic onto Pacific Highway and closed I-5 onramps in Middletown, Mission Hills and Old Town.

Trolley service also was suspended between Washington Street and Old Town. Metropolitan Transit System officials offered affected commuters bus rides between the two light-rail stations pending resolution of the police activity on I-5.

As of midday, northbound traffic on the partially closed freeway was in a state of gridlock as far south as state Route 163 in the Balboa Park area, said CHP public-affairs Officer Tommy Doerr. The southbound side of I-5 was more congested than usual as well, apparently due to spectator slowing.

About 12:45 p.m., the apparently suicidal man climbed off the edge of the interstate onto an ice plant-covered slope and was taken into custody for a psychological evaluation, said SDPD Sgt. Michael Stirk. The Highway Patrol then began reopening the freeway in the area.
