It’s time to put the pedal to the metal — the I-26 widening project is being fast-tracked . The project will add new lanes to Interstate 26 between Charleston + Columbia in order to alleviate traffic. The accelerated timeline was approved June 21.

I-26 is a vital commercial, personal, and tourist route , and the SC Dept. of Transportation has considered this project to be one of its top priorities .

Here’s a look at the latest on the widening project, by the numbers.

  • $600 million was recently approved by legislators to accelerate the project.
  • 2034 is the new projected completion date.
  • 6 years ahead of schedule — that’s how quickly things are now moving.
  • 70 miles of I-26 will be widened from Exit 194 to Exit 125.
  • 6 lanes — that will be the new total number of lanes after widening the currently four-lane highway.
  • $453.5 million of the funds will come from COVID-19 aid intended for roadwork.
  • $133.6 million of the funds will come from the state budget intended for rural interstates.
  • 30% increase — that’s about how much statewide traffic has risen over the last decade.
  • 22 million vehicles travel on I-26 between Charleston and Columbia per year, approximately.
