NORTH RICHLAND HILLS -- Driving down Davis Boulevard and Precinct Line Road should get a lot easier, beginning this summer.Street lights at 11 intersections along Davis and at three intersections along Precinct Line will be synchronized to allow for a smoother traffic flow. More motorists have been using Davis and Precinct Line because of construction on Northeast Loop 820 and because of population growth, said Jimmy Cates, public works operations manager. Traffic is backing up.The roadways are among the city's major thoroughfares and serve as a conduit to Farm Road 1709, Texas 26 and major highways.The City Council voted 7-0 on March 4 for a contract with Lee Engineering of Dallas for $51,400, without seeking competing offers to do the work. The city staff recommended the negotiated contract because of the price, Cates told the council. The council had allocated $95,000 for the synchronization."The new timing plan should help to relieve some of the congestion along these two corridors," Cates said.Traffic lights will be synchronized on Davis from Maplewood Avenue near Loop 820 to Precinct Line near Keller. Traffic Lights on Precinct Line will be synchronized at Amundson Drive, Glade Road and Rumfield Road. Work should take about five months.Lee synchronized the Davis Boulevard lights about four years ago, but they need to be synchronized every three to five years because of changes in traffic patterns, Cates said.Kelly Parma, Lee senior project manager, said the company will study traffic patterns during the morning and evening rush hours and during off-peak times. Researchers will also drive along the roadway during those times and use computer software to help perform calculations, he said.Some patrons at a hamburger restaurant on Davis said they look forward to seeing the lights synchronized.Thya Henderson, 23, said she lives off Davis. She said the lights often change to red just as she gets off Northeast Loop 820 and is driving to the next intersection. Traffic gets backed up, she said."I think that's really smart to drive through all the green lights," Henderson said.Michael Harville, 25, said he has lived in North Richland Hills his entire life. He said usually doesn't have too much trouble driving along Davis, except during rush hour. He said then traffic gets backed up because a left-turn lane is not long enough to handle all the vehicles."If they can pull it off, it will be great," Harville said.
