livermore and national geert -- laboratory. a tow truck came and put the vehicle back on its wheels and they moved it. hopefully we will get traffic going through here on south vasco road near the lawrence lab and just a little bit. hopefully this hasn't cause huge delays yet, we'll see traffic affected by other things, i want to mention now, let's talk about the commute on southbound 242. right near the willow pass road, there's an accident and traffic is slow. you can't get through, the left turn, i heard on the police radio. the best way to get onto 680 if you travel on highway 4 is to go to 680, and head south and bypass 242 southbound for the time being. because of the crash. we are looking at westbound 580, stop and go traffic on 205 and a 580, normal for livermore, getting in over the past from tracy it slow. were traffic looks good, heading into castro valley, look at interstate heading into castro valley, look at interstate 80 in both directions traffic is moving along well. the morning commute will be okay at the bay

they were classified for decades but a team at lawrence livermore labs tracked them down. one showed a massive explosion on the pacific ocean in 1958. >> looking at these films, we found a lot of different pieces of information had not been analyzed back in the '50s and we are discovering new things about these detonations never seen before. >> the u.s. government has now declassified the videos. one of the scientists at the lab says that he wants the public to see how powerful these tests can be so people might be more reluctant to use them. >>> in a few hours, the mayors of antioch, san ramon and danville will help deliver meals to homebound seniors in contra costa county. it's part of a new march more meals campaign launched by "meals on wheels." the program has been in the spotlight since it was revealed that it could be on the chopping block in president trump's budget plan. the proposal calls for eliminating a $3 billion community development grant which provides money for community development and antipoverty programs including "meals on wheels." >>> time now 5:15.

a team from the lawrence livermore national laboratory have located 65-hundred films. only a fraction have been analyzed and declassified... this is one of them. scientists say they are learning new information about the detonations as they review the original films. we've posted many of the videos on kron-4-dot-com.

in front of lawrence livermore lab at the west gate there was an overturned trailer being pulled by this train here with the van and the trailer on the wheels again. hopefullythis means traffic will start flowing through this again, which means they need to make sure they could get out there. but for the most part things are going to be okay. now let's move along to southbound 242 at concord avenue. they're clearing the accident now. in fact i think i just heard on the radio all lanes are open on southbound 242 at concord avenue. however there's been a lot of crashes here. westbound highway 4 right at port chicago highway. and just an educated guess, people are coming across here going kind of fast. they don't notice there's a bunch of slow traffic waiting here because of the crash and then there would be some wrecks. at least a couple of them according to chp in that area, so please give yourself extra time. we are also looking at livermore and dublin. it's going to be slow getting up to tracy on 205, but the rest of the commute looks good. northbound 101 right there at the off ramp wil
