Demolition of the northbound lane started last month on this bridge deck replacement project. Approximately half of the lane has been removed. There will be occasional traffic stoppages on I-70 overnight during the demolition work for motorist safety.
Traffic is alternating across the bridge using temporary traffic signals as the bridge is down to one lane during construction.
The project is estimated to be complete by Summer, 2023.
Motorists are now using a temporary roadway inside the median area of Centennial Lane after a traffic switch last month. Crews are working on the excavation and widening of Centennial Lane on the outside lanes and shoulder. Drainage structures are also being installed in this area.
On the west side of the project limits, along eastbound MD 108, work has started on the roadway widening along with the installation of new stormwater management facilities, as well as new curbs and gutters.
Expect frequent lane closures with a flagging operation on eastbound MD 108 Monday through Friday from 9 a.m. to 3 p.m. This project to improve intersection operations is expected to be complete by the end of this year.
The Office of Transportation developed a web-based interactive map for the MD 99 Corridor Investigation Report.
The State Highway Administration (SHA) recently revised the signal timing on MD 99 at US 29 and Rogers Avenue to address safety concerns involving westbound left-turners and the eastbound traffic. The speed limit on MD 99 was also reduced from 50 mph to 40 mph. SHA also approved exclusive left-turn phasing at MD 99 and Woodstock Road for traffic and safety reasons. MDOT SHA is currently working to fund and schedule the exclusive left-turn phasing project on MD 99 this year.
SHA will be trimming brush and trees and installing additional signage along MD 99 over the summer to mitigate sight distance issues at the existing stop-controlled intersections.
For additional questions and concerns, please contact David Cookson, Planning Manager.
