Starting this week, from 7 a.m. to 7 p.m., various Palo Pinto County roadways will be improved through seal coats. Highways affected will be U.S. 180, Highway 337, I20 service road and U.S. 281. "The Texas Department of Transportation seal coat program is the department's most cost-effective means of maintaining the Texas highway system," Natalie Galindo, TxDOT spokeswoman, noted. "A seal coat can extend the life expectancy of a given roadway by many years, at a fraction of the cost of resurfacing. On these rural roadways where a shoulder is present, smaller rock will be used to assist cyclists." When maintenance work necessitates two-lane roadways to be reduced to one, flaggers and a pilot car will lead motorists through the work zone. Motorists can plan their travel by viewing information on the closures at www.drivetexas.org. However, Sunday, these road work locations were not marked. "We appreciate motorist's patience while crews complete this maintenance work," she added. "During construction, alternate routes are encouraged."
