The South Carolina Infrastructure Bank Board voted unanimously to allocate up to $550 million for state highway construction projects, several of which are tied to the port of Charleston. The funding is part of a new law in which $50 million is allocated to the S.C. Department of Transportation annually, and then turned over to the infrastructure bank board to approve projects, issue bonds or access additional federal money.

The No. 1 project on the board’s list of priorities is the I-20/I-26 interchange northwest of Columbia. Other projects include upgrading the I-85/I-385 interchange in Greenville County; widening 16 miles of I-85 in Spartanburg and Cherokee counties; and widening 10.3 miles of I-20 in Lexington County. The complete list of projects still must be approved by the Legislative Joint Bond Review Committee.
