history. it will cost hundreds of millions of dollars and displace ten to 11,000 overnight subway riders. but foye says it's necessary. >> it's inconvenient. that is why for essential workers and first responders, we put this extraordinary level of bus service on. >> we're out there up close and personal with a lot of these people. you know, we don't know who is sick. we don't know who is not. >> reporter: a tough reality for drivers like paul gilmore who work on the front lines each day. his colleague is one of more than 100 mta workers who have died from the virus. >> this is very sad. you should see this man day in and day out. he's a nice gentleman, very good guy. at our garage it's the second family. it did hurt for sure. >> reporter: the effects of the pandemic on public transportation are palpable nationwide. in minneapolis, metro transit has seen a nearly 80% decrease in ridership since the end of february. in san francisco, buses were visibly vacant last month. and 60 of the city's 89

walking around who are touching the turn style, who are hoemding onto the pole in the subway car so they don't fall down. so you still have to be really careful. >> reporter: the mta says it's looking at several cleaning methods from using antimicrobial treatments to disinfecting services with uv light. >> mola lenghi in the new york city subway. above ground the national average for a gallon of gasoline now stands at about $1.80 a gallon. the lower price is a boon for drivers, but with millions of americans staying home these days there is now a glut of oil that can't be sold. and a lot of it is floating in tankers off the coast of los angeles. carter evans is there. >> reporter: oil tankers in the water surrounding america's largest port complex have turned this part of the pacific into a floating parking lot. on this day, 27 tankers, some carrying up to 1348 barrels of

unrefined oil, sat idle. >> this is roughly triple the normal number we would have when the port complex is on a normal day. >> reporter: captain kit monitors port traffic for the marine exchange for southern california. >> there is generally a population of three to five tankers out there waiting to come in. >> reporter: but you usually move them through pretty quickly. >> correct. >> reporter: because there's demand, which is what we're lacking now. >> correct. >> wide open. >> reporter: because of the stay-at-home orders, demand for gas has plummeted leading to a backup in the global supply chain. all those ships are out there because we don't have anywhere in california to put that oil? >> we have filled all of the storage tanks of refineries of california. but there's no more space. >> reporter: professor is an oil industry analyst at the university of southern california. with some refineries already shutdown, he fears what will happen. when cars are back on the road and demand increases. >> all of a sudden you go up and you don't have the refinery operation, you don't have the capacity. you're going to have shortages. formin at the gastion asn'73 an.

if we do aviation patrol from a helicopter we can see if there is anything that looks unusual. >> reporter: the perspective from the water really gives you an idea of how big these oil tankers are. but one of the best views of all of these ships is actually from a room back on shore. >> an miami bay for l.a. dump site number two. >> reporter: it's the marine equivalent of an airline control tower. >> we keep them from bumping into each other just like there were traffic lanes on the road, there are traffic lanes in the ocean. the ships all have them. >> reporter: how long could they end up being here? >> we have information that one may be there as long as the beginning of july. >> reporter: the beginning of july? >> yes. >> reporter: part of california's economy will start reopening friday, and that will boost demand for gas. but it will take weeks to clear this traffic jamb, meaning, it could be a long summer for the men and women patrolling these waters. i'm alex trebek here to tell you about the colonial penn program.
