Kohat is a major node on the N-55 Indus Highway that connects Peshawar to Karachi, and the N-80 highway that connects Kohat to Islamabad. The Kohat Tunnel was completed in 2004, and connects the southern districts of Khyber Pakhtunkhwa to Peshawar. Constructed with Japanese assistance, the tunnel drastically reduced travel times across the Kohat Pass.
