The Interstate 10 Marsh Station improvement project is being completed in phases as outlined below. Please click on the links provided to learn more about each phase.

• Improvements to a segment of Interstate 10 approximately 15 miles west of Benson (mileposts 288-291) are in progress.
  

• Completed: Removal of the Union Pacific Railroad bridge, located about one and a half miles west of the new Marsh Station traffic interchange was completed on March 9, 2013. Now that the bridge has been removed, most commercial trucks will be able to travel on I-10 in the project area and they will no longer need to use the detour.
• Completed: A new Marsh Station traffic interchange was constructed to accommodate trucks with a clearance of 16.5 feet and the old Marsh Station Bridge was removed. The old Marsh Station traffic interchange required trucks over 15 feet to use State Routes 83, 82 and 90 as a detour off Interstate 10. The project began in November 2009. The new Marsh Station traffic interchange was opened on Monday, December 20, 2010. Additional work, such as painting and landscaping, was finalized in February 2011. The old Marsh Station Bridge was removed overnight Friday, April 8, 2011.
