Shield Being Installed Under MD 94 Bridge to Collect Debris; Motorists Advised of 14’6” Height Restriction on I-70 During Project
(June 28, 2022) – The Maryland Department of Transportation State Highway Administration (MDOT SHA) will activate three new temporary traffic signals on the MD 94 (Woodbine Road) bridge over I-70 in Howard County. To alert motorists about the upcoming activation, the signals will begin flashing on Thursday, June 30 through Tuesday, July 5.
Starting at 9 a.m. on Wednesday, July 6, crews will activate the two signals at each end of the MD 94 bridge, as well as a third signal at the top of the westbound I-70 exit ramp onto MD 94. The signals will alternate traffic in both directions using one travel lane across the bridge during construction. Crews will start work on northbound MD 94 before moving to southbound MD 94.
With the new traffic pattern in place, MDOT SHA will lower the speed limit on MD 94 between the MD 144 (Frederick Road) roundabout and the Old Frederick Road roundabout from 45 mph to 35 mph for motorists’ and workers’ safety. The new speed limit goes into effect Thursday, June 30.
The work is part of a $4.7 million project to replace the MD 94 bridge deck. The project began this spring and is expected to be complete in summer 2023. Learn more by clicking here.
Crews also are installing a shield under the MD 94 bridge to collect any debris from the removal and construction of the bridge deck. The shield will be in place for the duration of the project. The shield will result in a reduced height clearance for vehicles traveling on eastbound and westbound I-70 under MD 94 to 14 feet, 6 inches – a reduction from the current height of 17 feet. Vehicles exceeding the height restriction should use the MD 94 exit to travel over the bridge and continue onto I-70.
MDOT SHA contractor, Rustler Construction Inc. of Upper Marlboro, will use electronic signs, roadway signs, cones and barrels to alert motorists about the new traffic signals and height restriction.
MDOT SHA works hard to maintain safe traffic mobility in work zones for our crews as well as our customers. Drivers need to stay alert, focus on driving and look for reduced speed limits as well as other driving pattern changes. Please drive like you work here and slow down in construction zones.
Motorists in need may dial #77 on their mobile device for roadside assistance.
