Diboll relief route
This project is dedicated to improving safety and mobility on US 59 near the city of Diboll. Studies for the Diboll Relief Route began in the 1990’s and concluded with TxDOT receiving approval of the schematic and environmental studies in 1999. TxDOT soon began purchasing right of way; however, due to budgetary constraints, ROW acquisitions were stopped.
Development of the Diboll Relief Route was revived after being identified as the top priority of I-69 development in Angelina County by the I-69 Angelina and Nacogdoches Counties Committee in 2013. TxDOT held an open house on Jan. 22, 2015, to display the schematic that had been updated to meet current interstate standards and to gather information and comments from the public. After the open house, TxDOT compiled the comments and made further revisions to the schematic to address comments. Some of those changes included lengthening several ramps to provide access to landlocked parcels, reconfiguring the south interchange to a more conventional diamond interchange and providing a city street connection from Old Diboll Highway to the FM 2108 Interchange. Please see the links below for the approved schematic and public meeting summary, and resolution of support from Angelina County.
