Mobile County Road 39 - McDonald Road

Home » Guides » Alabama » Mobile County Road 39 - McDonald Road

McDonald Road carries Mobile County 39 between U.S. 90 at Irvington and Mobile County 32 (Three Notch Road / Gold Mine Road) near Dawes. The two-lane roadway was upgraded to a four-lane divided highway between 2003 and 2005 to improve access to the Irvington and Bayou La Batre areas in conjunction with Interstate 10, U.S. 90, and Padgett Switch Road south (Mobile County 23). A six-ramp partial-cloverleaf interchange between McDonald Road and Interstate 10 opened on January 12, 2005 at a cost of $16 million.1 The original two-lane crossing over the freeway was removed in 2004.

Mobile County 39 ended at U.S. 90 until the June 2009 completion of its alignment southward to Half Mile and Padgett Switch Roads. The four-lane roadway directly ties into Padgett Switch Road (Mobile County 23) leading south to Alabama 188 near Bayou La Batre.

Completed and opened to traffic in June 2009, Mobile County 39 enters the folded diamond interchange with U.S. 90. A CSX Transportation railroad line parallels U.S. 90 along the southbound side, necessitating the need for ramps to the north of U.S. 90. Additional ramps tie County Road 39 with Park Boulevard west to Mobile County 19 (Irvington Bayou La Batre Highway) and east to Mobile International Speedway. Gibson Road ties into the northbound side from Padgett Switch Road (Mobile County 23). Photos taken 06/11/06, 10/01/09.
