Interstate 205 Business (I-205 Bus.) is a locally maintained business route. It locally follows 11th Street, the historic four-lane alignment of US 50, through Tracy. The route begins at a split with I-205 west of the city. After passing through downtown Tracy, it curves northeast at a junction with former SR 33, which has been truncated to the south at I-5. The final stretch of I-205 Bus. runs diagonally to a merge with I-5, which comes from the south and continues northeast along the former US 50 alignment. The east end of I-205 Bus. is about 0.75 miles (1.21 km) southwest of the end of I-205; normally, I-205 Bus. would return to I-205 at both ends, but, here, I-205 and I-205 Bus. both end at I-5.[2]
