Mississippi Highway 67

The current 4-lane expressway represents the third realignment of Highway 67 during its history. Highway 67 previously existed as a 2-lane road, starting at I-10 Exit 41 south of Woolmarket, and proceeding north past the village of Success, before turning west to end at Highway 49 about a mile south of its present terminus.

I-110 at its northern terminus, with the roadway continuing as Highway 15 and Highway 67 in D'Iberville

Prior to the opening of Interstate 10 in the 1970s, Highway 67 continued southeast from Woolmarket to intersect Highway 15 in D'Iberville, and the two routes crossed the now demolished bridge across the Biloxi Back Bay, and then following Caillavet Street to Highway 90, where both routes ended.

The old Highway 67 was bypassed with a new 4-lane highway that now carries the Highway 67 designation from US-49 in Saucier to a new southern terminus at Highway 90 near downtown Biloxi. Highway 15 joins Highway 67 north of Interstate 10 in D'Iberville, and both routes proceed south on the same alignment to their southern termini at the I-10/I-110 interchange. The highway continues south into Biloxi as I-110.

Construction on the Highway 67 relocation project began in 2002 and the road officially opened to traffic on January 16, 2009. The entire project cost approximately $72 million.[2]

The entire route is in Harrison County.
