Special routes of U.S. Route 90

A total of seven special routes of U.S. Route 90 exist.

Texas

All of the alternate and business routes within Texas are maintained by the Texas Department of Transportation (TxDOT). U.S. Route 90 has one alternate route and two business routes within the state. Along US 90, TxDOT identifies each business route as Business U.S. Highway 67 followed by an alphabetic suffix. Along Texas U.S. routes, the alphabetic suffixes on business route names ascend eastward and northward. There are gaps in the alphabetic values to allow for future system expansion or for decommissioned routes. The alphabetic naming suffixes are included as small letters on the bottom of route shields.

It crosses the Mississippi River on the Crescent City Connection and runs along the Westbank Expressway west of the bridge and part of the Pontchartrain Expressway in the New Orleans Central Business District. On the other hand, U.S. 90 runs along surface streets through New Orleans, crossing the Mississippi on the older and narrower Huey P. Long Bridge.

Florida

Pensacola alternate

U.S. Highway 90 Alternate
Location:	Pensacola, Florida

U.S. Highway 90 Alternate is an east–west bypass route of Pensacola, Florida. It is also known as Nine Mile Road, as it is located approximately nine miles north of downtown Pensacola.

Interstate 10 has largely supplanted the role of U.S. 90 Alternate as a bypass route. The road today serves largely as a commercial corridor for the northern suburbs of Pensacola. However, following the partial destruction of the Escambia Bay Bridge by Hurricane Ivan, U.S. 90 Alternate resumed its role as a cross-country bypass route for a short time.

The entire route is in Escambia County.
