alodge the end of the stretchway and it was 58th of a mile where the drain cover went into it. they are looking for excessive ware and damage defects anything to indicate why it came loose. state police have taken the 200 pound metal disk into possession. now focused on figuring out how it came loose and ended up airborne crashing through the front and rear windshields of this car. killing 35-year-old katelyn clavette as she drove through the o'neill tunnel governor baker. >> our hearts and thoughts go out to the family that through an incredibly bizarre event lost someone today. >> reporter: state transportation crews spent the day checking more than 500 other openings on the state highway system within boston city limits. making sure they are secure.

morning as clavette headed southbound. police say the cover labeled boston drain came from a hole just at the tunnel exit. after it hit, the car continued out into the left lane of the expressway. eventually hitting a wall along the shoulder. we spoke with terry granahan who was in the rush hour traffic. >> the the state police were blocking us so no one would hit the manhole cover and there's steel i imagine if it hit the car it would have hate person it would do some serious damage. >> reporter: of course there are surveillance cameras all along the expressway and people are going through the footage particularly before this incident look for anything that might point to why that cover was not secured on the hole. in boston, christina hager wbz news paula david back to you. >> thank you. early this morning the womanwas killed was likely on her way to work. >> she was a teacher in milton

inspected every two years and an emergency inspec was done on more than 500 of them today massdot and state crews performing a emergency inspection check more than 500 manhole covers after one becamedislodged this morning killing a driver. this is not the first time massdot has undertaken the project n2007 there were 5 incidents -- in 2007 there were five incidents where cars were hit by manhole covers and storm grates including this horrible scene on 128. >> out of extreme caution we are inspecting the roadway mass highway is he inexpecting -- is inspecting the roadway completely to make sure the same event couldn't occur again. >> reporter: since then they say they have inspected manhole covers every two years. manhole involved in today's incident was last looked at on june 12th, 2014. manhole events are far from common but they happen just

cover caused a school bus accident. last year a springfield truck driver was killed in new york when a manhole cover flew through the windshield. now manhole covers can become dislodged for any number of reasons and sometimes it's because of issues underground. back in 2005 a study in massachusetts showed an average of 69 manhole incidents per year of course most of those do not impact the roads. lauren leamanczyk wbz news. >> thanks stay with wbz news as we learn more about why this accident happened and we will bring you the latest as soon as we get it. we have more breaking news tonight out where police are investigating a hit-and-run. boy was on his bike when i was -- when he was hit on lawrence street and the driver kept going. he is hospitalized with severe injuries and police are trying to track down the driver. we are tracking dangerous cold this weekend we are looking at wind chills as low as 25 below zero.

and this is no joke. >> no this is about as cold as it gets. so i look at these types of days days we have big severe weather and it's a short amount of time where you pay attention to the weather and treat it with respect and move on next week things will warm up. as we look towards saturday and sunday, wind chill warnings for the area and advisory for cape cod and islands and wind chills will not be as harsh but cold enough. here's the arctic front the leading edge of the coldest of the code pouring down out of canada and they will arrive right around midday on saturday. so as we look towards tomorrow, the morning is cold but we don't have too much wind after lunch that's where the winds increase and wind chill values drop and by the time we head towards dinner we are looking at 20 to as much as 30 below zero for the wind chills. you can see frostbite in 10 to 15 minutes in conditions like that. avoid extended amount of time outdoors and exposed skin if you are heading outside and making sure the pets are indoors for as m as possible. sunday morning in the core of that cold and then as we head

day it's very cold but windy minimum ishes and the wind chill will be less of a factor at that point. looking at -- diminishes and the wind chill will be less of a factor at that point. sunday we are in the freezer for lookly the coldest valentine's day in the area. monday snow arrives by the end of the day. so wintry forecast with a full look coming up in a few minutes. >> appreciate it thanks. commuter rail trains will be running at odd hours or actually idling through the night because of the cold. they say keeping the equipment running will prevent mechanical issues in the cold weather. coast guard warning fishermen. temperatures this low will cause heavy freezing spray off the water which can be dangerous to the fishing boats. the biggest threat is to boats closer to shore. a developing story in dorchester where a man was killed in a shoot out with police. police believe the started -- this started with an incident in apartment where two men were shot.

and then came upon a man with a gun carrying another man who had been shot in the leg. officers told the armed man to drop the gun three times. instead he opened fire. >> nobody likes to take a life. but if you are going to point a gun at one of our officers, in the way he did, obviously we will protect ourselves and we are going to neutralize the threat. >> the man's name has not been released but he had a long record. 57 arrests. tonight there's a new lawsuit trying to stop the everett casino not from boston but somerville. suit says the wynn resorts project is too big and will water front. somerville challenging the casino. up next a bumpy flight. >> and it never got off the groundch the airport accident that put some travel plans on hold. >> a 10-year-old entrepreneur. north shore bow who -- boy who business.

a jetblue plane parked and waiting for take off was damaged when it was hit by a fueling van at logan this morning. a passenger told wbz the driver of the van had just gotten out plane. no one was hurt and the passengers did have to be taken off the plane and put on another flight. a robot built by the ocean graphic institute will be used to search for data recorder for el faro. the robot can can produce high quality maps of the ocean floor and the data recorder he could explain why it sank killing 33 crew members. several with ties to new england. a another skimming device on a gas pump this time at a shell station in quincy.

wired and so the credit card numbers scanned could be down loaded remotely. this is at least the 4th gas station where skimmer has been found. well it's going to be tough to step outside of the car to get gas. >> standing this and people will be happy it's legal now to get the clips. >> the problem is not every gas station has the clip that automatically locks it in place so you drive around in circles until you find it. >> i fueled up and i am not going outside. it's going to be brutal and making sure the gas tanks are more than quarter full are a good idea because sometimes cars not starting is probably going to be an issue heading towards sunday morning. look towards valentin tine's day wore -- valentine's day worcester and boston pho forecasting freezing temperatures. of all the years this could be the coldest valentine's day that we have experienced in the boston area. we will share it together.

18 in worcester and 19 nashua. chilly for the most but the cold stuff the source of it is up towards the arctic and that air is making a move towards us tonight and arrives around midday tomorrow. and right now you can see the arctic front lined up with the great lakes and a storm system along the delmarva peninsula bringing snow up across the area during the overnight hours. so chance for snow showers and best chance for a period of steadier snow say cross the cape and islands. not expecting big total but slick travel possible during the overnight. it's gone by tomorrow morning. accumulations of a coating to a couple inches and scattered coatings inland is what we expect overnight when it comes to the snow. some just brushing it aside by tomorrow morning. overnight low temperatures in the single digits. and then tomorrow we track the arctic front as it crosses the region. so many have asked if i will run with the boston marathon running who would i go outside tomorrow morning. it's not going to be pleasant but it will be in the teens. but the wind is not strong yet. i would finish by noon because

winds start to funelling in from the north and west and temperatures fall during the afternoon when usually we have the highs. and by the evening we are on either side of zero by 8 p.m. and that's without the wind. so it's going to be very cold night for any of your saturday night valentine's day plans and when you add in the wind we are looking at wind chills from 20 to 30 below zeroch the worst is tomorrow evening -- zeroch worst is tomorrow evening tomorrow -- zero. the worst is tomorrow evening tomorrow night into sunday morning. the winds will start to decrease and as we head past lunchtime wind chill values are closer to zero. not nice but the danger not nearly as high on sunday afternoon. looking at air temps. well below zero region wide on sunday morning. only area that stays above zero lower outer cape as well as nantucket and only by a couple degrees. and the high temps in the single digits to lower teens on sunday. so indoor plans a great thing certainly and if you are taking care of the pets let them outside briefly and get them back inside. looking towards president's day

we will start off cold and the clouds will increase and there's a chance of snow by the evening. and the next storm system that we are tracking is a potent one but the track looks to bring snow to ice and rain on tuesday as many areas will be warming through the 40s. here's the accu-weather 7-day forecast and next week a chance to thaw out from a high of 10 on sunday and 46 on wednesday. so ups and downs in the forecast. david and paul. >> that's the opposite of what you think. you think tomorrow is cold but that's when he says you should go running. because then it's going to be too windy. >> we can make it easy i am not i mean. >> we won't have to worry about that but hockey weather. >> levan reed the only -- reid on tv. >> i won't run outside either. that never will happen thanks paula. [audio not understandable] why did the b's play on the

when they play on the road they are 17-5-3 and think the bruins like the away jerseys. last night the team was in winnipeg and this is how you start a 6-game road trip. they put biscuit in the bass kit 6 times -- bass kit 6 times -- basket 6 times. bergeron filled it up 2 goals on the night and the bruins get a must needed win and beat jets 6-2 the team is off tomorrow and they will take on -- the team is off tonight and in minnesota tomorrow and bergeron is not scheduled to play. he is questionable. hey man you are an all star. celtics guard isaiah thomas is in toronto for the all star weekend and received the jersey a couple nights ago at the garden and is ready to represent. this is his first all star appearance and he promises to take it all in. isaiah will take part in the skills competition tomorrow night. so we did a poll in the sports office and what else can they
