The tunnel on Airport Road will be undergoing routine maintenance and cleaning beginning Sunday. The northbound lane (which heads towards Peters Creek Road) will be blocked off and the southbound lane (which heads toward Williamson Road) will be routed to accommodate two-way traffic for approximately 30 days; after completion of the northbound side, the southbound tunnel lane will be blocked and the northbound lane will be routed to accommodate two-way traffic. The entire project is expected to take approximately 60 days.
