photoCity Councilman Scott Griggs today released plans for converting Tyler and Polk streets in Oak Cliff to two-way streets.

“I have identified funding for both the final design of the conversion and its construction,” Griggs states in his monthly newsletter. “You will likely see the transformation of those streets to two-way thoroughfares one year from now.”

The conversion is estimated to cost $2,637,440 if traffic signals were installed at the ends and $2,138,300 if roundabouts were used at the ends.

The plan calls for turning Tyler and Polk into four-lane roadways with two northbound and two southbound lanes each. The two-way conversions would occur where Sylvan and Tyler split into two streets just north of Davis and south of Twelfth, respectively.

An average of 11,918 cars per day travel Sylvan and Tyler. The two-way change would slow traffic make the streets safer for vehicles and pedestrians, Griggs says.
