A 377 update from a reader who lives in Keller:
Keller city engineer, Keith Fisher recently gave a progress report on the Highway 377 construction. Mr. Fisher stated that the project manager has a target date of April 1st for opening all southbound lanes that are currently under construction. The light that has been installed at the Johnson Road intersection should be operational by this time also. A new intersection will be established at Mt.Gilead Road and the new Katy Road rail crossing. The current plan for the old rail crossing at Caylor Road is to re-establish the rail crossing providing access to Katy Road. A short term completion date for the Mt. Gilead Road and Caylor Road projects has not been released. Once completed there will be stop lights at Mt. Gilead, Johnson, Keller-Hicks and Golden Triangle. Mr. Fisher expects these lights to be set on a timing pattern to allow for a smooth flow of traffic, similar to the lights along Keller Parkway.
