Celina is a city in Collin and Denton counties, Texas, United States. As of the 2010 census, Celina had a population of 6,028, up from 1,861 at the 2000 census.
Celina is undergoing rapid growth. Having never before had any kind of retail chain other than two fuel stations and a small Chevrolet dealership, Celina saw a Sonic restaurant completed in 2003. In October 2005, Brookshire’s broke ground for construction of a new grocery store, where for 18 months prior only a sign had stood announcing the “future home” in the cow pasture at the corner of Preston Road and County Road 91. A McDonald’s restaurant opened in October 2011. Since 1999, much of the country land has tripled in price.
With the continuous building of middle and upper scale homes in Celina and the nearby towns of Prosper (south of Celina) and Gunter (north of Celina), the volume of traffic has increased dramatically. Between January 2004 and July 2005, the rush hour commute on SH 289 from Celina to SH 121 lengthened from approximately 20 minutes to almost 50. As of 2011, construction to widen SH 289 to a six-lane divided highway north from SH 121 to Hwy 380 (8 miles (13 km) south of Celina) is underway.
