The Harris County Precinct 4 project extends Holderrieth Road as a four-lane concrete pavement section from Hwy. 249 in Tomball to Calvert Road. The project was scheduled to be complete in late November but has been delayed to February 2019 due to utility conflicts and poor weather conditions, Precinct 4 officials said.
