COSTELLO: Rio's challenges are relentless. Zika, crumbling structures, crime. With less than 5 days left until the opening ceremonies, can the city deliver? CNN's Shasta Darlington live in Rio with more for you. Hi, Shasta.</s>SHASTA DARLINGTON, CNN INTERNATIONAL CORRESPONDENT: Hi, Carol. I actually want to start with a little bit of good news, we haven't had so much of that. Right behind me is a brand new metro line that we thought, for months, might not open in time to connect all of the hotels here in the touristy part of the city, with the Olympic Park 19 miles away. Well today it's opening its doors, at least for ticket holders. And that means that a trip that can take up to two hours in congested roads is now going to be cut down to about a half an hour. The bad news is that it won't open up for the rest of the city until after the games. We've already seen people behind us getting turned away when they try to go in. We also have had, unfortunately, some bad news on the venue side. While the venues were delivered largely on time, some of them have since been damaged. At first it was the Olympic Village. We had heard about all the problems there. Well now the main boat ramp at the marina where the sailing event and the windsurfing events are going to take place, it was ripped apart by strong winds. And on the same day, this very strong weather front also damaged some T.V. studios on Copacabana Beach right next to the volleyball -- the beach volleyball stadium. Those studios were damaged, they're having to build a barricade around that. It just seems like as soon as they get one thing done, they've got to fix something else, Carol.</s>COSTELLO: All right, Shasta Darlington reporting live from Rio this morning. Thank you for joining me today, I'm Carol Costello. AT THIS HOUR with Berman and Bolduan after a break.
