Road Enhancements

MD Route 32 Improvements

MD 32 (Patuxent Freeway) at Dorsey Run Road

Single lane closures as needed on MD 32 and Dorsey Run Road between 7 p.m. and 6 a.m. There will also be single lane closures during the day on Dorsey Run Road. MDOT SHA will close one ramp at a time to perform the work which will require a total ramp closure until the work on that ramp is completed. Here is the estimated schedule of the remaining ramp closures: 

  • Ramp C (Westbound MD 32 to Dorsey Run Road) - starting in mid-September
  • Ramp D (Dorsey Run Road to Westbound MD 32) - starting in November 

MD 32 (Patuxent Freeway) between Linden Church Road and I-70 – updated 10/5/2 - MDOT SHA will continue moving traffic barriers on MD 32 (Patuxent Freeway) at the Burntwoods Road interchange during overnight work scheduled this Sunday, October 10. 

Starting at 9 p.m., crews will have a flagging operation and single lane closures from south of River Valley Chase to north of Triadelphia Road, a span of one mile. The overnight operation will end by 5 a.m. the following day. The work is scheduled for three consecutive nights - Sunday, Monday and Tuesday.

The concrete traffic barriers are being moved to enhance motorist and work zone safety. 

MD Route 99

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.
