Motorists in Pflugerville will soon see new types of street signs on city streets, featuring a new color and a distinct city logo.

Prompted by new federal requirements outlined in the Manual of Uniform Traffic Control Devices, which dictates the specifications for city street signs, Pflugerville's Public Works Department workers began installing new signs around town June 28.

Motorists and residents may notice signs that include uppercase and lowercase lettering and a larger font for street names. Road signs are also wider and include a two-block range.

City officials said a government study found that upper and lowercase letters are easier to read, which prompted the change in federal requirements.

Assistant City Manager Tom Word said the new federal requirements presented the city with a rare branding opportunity, including some changes unique to the city.

"The signs are a distinct blue to further differentiate for residents and guests when you are driving in Pflugerville, and they incorporate the use of the Pf sticker," Word said.

Officials with the public works department anticipate having city signs converted by December 2012, five years before the federal deadline.

The new signs are visible now along many streets in and around Pflugerville's downtown area, including Main Street.
