TAMPA — A week after a mother and daughter visiting from Ohio were killed while walking across Bayshore Boulevard, Tampa police were still out enforcing new lower speed limits along the scenic commuter route.

The city of Tampa moved up plans to lower the speed limit on Bayshore from 40 mph to 35 mph after Jessica Raubenolt, 24, and her 21-month-old daughter were killed May 23. They were struck, police said, by a teen driver who was drag racing.

In the week since then, police have issued 23 citations, up 34 percent over the same period last year, and 281 warnings, up 44 percent over last year.

Stepped-up enforcement already was under way along Bayshore before the fatal collision, with Police Department figures showing traffic stops overall increasing 55 percent year over year for the five months from Jan. 1 through May 23.

During the same period, the number of warnings and citations was up 43 percent and the number of injury crashes down 20 percent, police said.
