All lanes of Interstate 70 have reopened after a water main break near Jennings Station Road caused a large sink hole to form Wednesday afternoon.
Traffic on westbound I-70 was down to one lane through rush hour and much of the evening.
Missouri American Water crews worked well into the night to fill the hole, re-pave the road and reroute water to local customers.
Water Company Spokesperson Ann Dettmer says the 12 inch line broke because it was old and overused. Dettmer says as the ground dries up, it doesn't provide as much support.
Engineers will consider whether to replace the main or reroute water service around it permanently.
There's good news for drivers in north county. Missouri transportation officials report that all lanes of westbound I-270 have reopened after a broken water main had shut it down for several hours.
Just before 10 o'clock Monday night police closed westbound I-270 because of the broken main at Old Halls Ferry. The closure caused traffic to back up all the way into Illinois.
By 1 a.m. Tuesday, one lane had reopened.
At about 2:30 Tuesday morning, MoDOT reported that all lanes had reopened.
The water main burst overnight Thursday at Market and 17th Streets near the main post office.
Water began gushing into the intersection of Market and 16th around 10:30 p.m. Wednesday, just as fans were beginning to leave a Bon Jovi concert at the Scottrade Center.
The water was shut off around midnight, but there is significant damage to Market Street. It is closed between 16th and 17th streets.The main has been shut off and crews are working to repair the pavement.
The parade and run routes are expected to go through the intersection on Saturday. Both the water and street department said there's going to be a run and parade, but they will have a backup plan in case the job isn't finished.
Southbound Hanley Road will be restricted to a single lane as crews work to repair the break. The break is immediately south of Forest Park Parkway. Drivers are encouraged to use Brentwood, Big Bend, or 170 as alternates.
Work is expected to continue until Friday morning.
