DALLAS (CBSDFW.COM) — A major ramp shift on Interstate 30 related to the Dallas Horseshoe Project will begin Sunday.

Drivers commuting down westbound I-30 to I-35E will have to decide by Ervay Street which way they want to go, according to the Dallas Horseshoe Project. The shift begins at 9 p.m. and should be completed around 5 a.m. Monday.

Drivers needing to go southbound on I-35E will stay in the right lanes to exit 46A, the new bridge to I-35E. Those needing to go northbound on I-35E or continue on I-30 will stay to the left. This is the opposite of the current traffic pattern.
