Sherman opens bids for Hilre Drive extension Sherman's Hilre Drive may soon get an update aimed at alleviating traffic concerns in northwest Sherman. The Sherman City Council recently approved moving forward with requesting bids for the extension of Hilre Drive to North Travis. The move comes as city officials attempt to address an awkward and potentially dangerous spot on North Creek Drive with two stop signs in close proximity of each other. "This extension is needed for safety purposes so that we can eventually close off Knollwood where it intersects with North Creek Drive," Sherman Engineering Director Wayne Lee said.
