City Secretarv City of Texas January l8, 2000 The Honorable Bobbie Mitchell Mayor, City of Lewisville P.O. Box 299002 Lewisville, Texas 75029-9002 RE: SPEED LIMITS on S.H. 121 By-Pass Dear Mayor Mitchell: Recently your City received information from TxDOT concerning establishing 55-mph speed zones along S.H. 121 By-Pass between Denton Tap Road and MacArthur Blvd. That portion of S.H. 121 By- Pass is within the corporate city limits of Lewisville; however, the majority of the development that is taking place along that portion is within the City of Coppell. As you are aware, Coppell abuts the south side of the eastbound frontage road of S.H. 121 By-Pass. Current development along the south side of S.H. 121 By-Pass includes five residential subdivisions and one elementary school and one middle school. Because of the development within the City of Coppell, between Denton Tap Road and MacArthur Blvd., the City of Coppell respectfully requests that the City of Lewisville not approve any ordinances establishing speed limits greater than the current 45-mph. It is our opinion that the higher speed limits could be detrimental to the safety of the motoring public as they attempt to maneuver into and out of the adjacent residential developments, the elementary school and the middle school. It is my understanding that this item will be discussed at your January 18, 2000 City Council meeting for approval. Again, prior to considering changing the speed limits along S.H. 121 By-Pass, please take into consideration the concerns of the City of Coppell and its citizens.
