Bethany and Cedar Mill commuters who use TV Highway have a new reason to watch their speed: two photo enforcement cameras activated July 13 have already generated 607 citations in their first three weeks.

The cameras sit at the intersections of Tualatin Valley Highway with Southwest Millikan Way and Southwest 160th Avenue, monitoring eastbound and westbound traffic. Between July 13 and Aug. 3, the devices triggered 827 times. After a photo enforcement officer reviewed each activation, 607 resulted in mailed citations, according to Beaverton Police Sgt. Chester Lamb.

One driver was clocked at 98 mph.

"So far, 98 mph has been the highest speed the cameras have captured," Lamb told the Beaverton Valley Times.

The city tested the cameras starting July 6 but held off on tickets and warnings until July 13, giving drivers a week's grace period. The cameras enforce both speed limits and red lights. For red-light violations, a citation is issued only if a motorist crosses the first line of the painted crosswalk after the signal has turned red.

Beaverton already operates photo enforcement at four other intersections: SW Beaverton-Hillsdale Highway at SW Griffith Drive, SW Walker Road at SW Cedar Hills Boulevard, SW Scholls Ferry Road at SW Hall Boulevard and SW Allen Boulevard at SW Lombard Avenue. The TV Highway additions bring the city's total to six camera-equipped intersections.

Nearby Sherwood began issuing its own photo enforcement tickets on June 22 after testing mobile cameras on SW Oregon Street starting in May. Beaverton has not announced a public meeting or review date for its expanded camera program.

The Beaverton Police Department's Facebook video announcing the TV Highway cameras had drawn 40,000 views and 632 reactions by Wednesday, Aug. 5.
