buses are supplemented with rapid buses with limited stops. The Rapid routes largely follow the route of the local buses, with some variations; at times when the 5R and 9R operate, the 5 and 9 are cut back to a shorter route. The 5R, 9R, and 28R operate only on weekdays until 7pm; the 14R and 38R operate every day until 7pm. Express bus lines Muni operates several types of express routes. Twelve routes operate between outer neighborhoods and downtown. The local sections in the outer neighborhoods overlap with local routes of the same number, while the non-stop express sections operate on expressways or major arterials. They operate only during weekday peak hours, with service only in the peak direction. Buses in the opposite direction run deadhead except for the 8AX and 8BX, which are paired with the local route 8 in the non-peak direction. Eight of the express routes are paired into 'A' and 'B' types, which have different local segments on the same corridor. All express routes except routes 1X, 8AX, 8BX, and 78X are suspended during the COVID-19 pandemic. Three express routes provide specialized service. The 76X, which runs only on weekends and holidays, provides service to recreational and tourist areas in the Marin Headlands. The 78X and 79X provide service to the Chase Center; they run only before and after events at the arena. Three additional routes provide shorter-distance express service between the Caltrain commuter rail terminal at 4th and King station and business areas near Market Street. Like the outer express routes, they operate only at peak hours. The 81X and 82X operate only in the peak direction (the 81X operates only in the morning peak); the 83X has bidirectional service. Owl bus lines Owl routes provide night bus service from 1am to 5am daily (including holidays) as a part of the Bay Area's All Nighter network. The 90 Owl route is a combination of the daytime 47 Van Ness and 9 San Bruno routes, while the 91 Owl route is a combination of the daytime K Ingleside, 8 Bayshore, T Third, 30 Stockton, and 28 19th Avenue routes. The 5 Fulton, 24 Divisadero, 44 O'Shaughnessy, and 48 Quintara-24th Street Owl routes are truncated from their daytime counterparts. Route 714 is part of the Early Bird Express system, which provides service while BART performs seismic retrofit earthquake work in the Transbay Tube. It runs a
