Construction work on two Lawrence intersections and new traffic lights at three locations are scheduled to be completed by fall.
The intersections of Ninth and Emery, 23rd and Harper and 15th and Crestline all will have new traffic signals installed by Oct. 1, city engineer Terese Gorman said.
The intersection at Ninth and Emery has been under construction since spring, closing through traffic from Iowa to Emery on Ninth. Ninth Street is being widened from two lanes to four lanes from Emery to Avalon Road.
The widening of the street and the installation of the lights should be completed by Sept. 4, Gorman said.
The city also plans to have new traffic lights and a turn lane installed at 15th and Crestline by early September. A median on 15th street is being removed and a left-turn lane is being installed for traffic turning from 15th onto Crestline, Gorman said.
Traffic lights originally were scheduled to be installed at 23rd and Harper by Sept. 1, but that date has been reset for Oct. 1 because the city is waiting for equipment to arrive.
The city also plans to install traffic signals at the intersection of 17th and Massachusetts, where an 86-year-old woman was struck by a car in January. The woman, Theresa Knight, later died of head injuries.
The project is still in the design phase and, because of the three-month period required for manufacturing the lights and 30-day period for installation, it probably will not be completed until Feb. 1, Gorman said.
