As part of ongoing improvements at Harrisburg International Airport (MDT), Phase 1 of a roadway project will begin Monday, March 30 and continue through Wednesday, April 22, 2026.

During this time, there will be lane restrictions along Terminal Drive as you enter the airport. Traffic will continue to flow, and access to the terminal, parking garage, and all airport facilities will remain open.

What to Expect

Travelers may experience minor delays when approaching the terminal, particularly during busier travel times. Clear signage and traffic guidance will be in place to help keep everything moving safely and efficiently.

Keeping Travel Easy at HIA

This work is part of HIA’s ongoing efforts to improve and modernize the airport experience—while continuing to provide the safe, convenient, and less chaotic travel experience our passengers expect.

A map outlining the temporary traffic pattern and work zone is included below for reference.

We appreciate your patience as we continue making improvements for our travelers.
