Road Enhancements

MD Route 32 Improvements (Phase I and II)


Detour 2

The Phase I project (MD 108 to Linden Church Road), as of September 2019 is substantially complete. The contractor is removing approved erosion and sediment controls from the work zone. Crews are also working on punchlist items to close the project which include lighting, CCTV, signs and landscaping.

The Triadelphia Road Bridge replacement (Phase II of Route 32 expansion) began in June of 2019. During the full year of construction, a partial closure of the bridge will occur. Westbound traffic will be maintained, however, eastbound traffic will be detoured using Ten Oaks Road, northbound MD 32, and Rosemary Lane (see above map). This detour and partial closure will be in effect through summer 2020. 

Traffic is now using the new westbound span of the Triadelphia Road bridge. The new sidewalk is also open on that side. The demolition of the existing eastbound span continues. The new bridge is on-schedule and expected to reopen to two-way traffic this summer. 

The contractor completed caisson drilling for abutment A at structure S6 (future bridge over the Middle Patuxent River) and will next drill for the center pier. Crews started placing new storm drains near the access road #4 tie-in at MD 144. 

In the southern work zone, a stream diversion is in place for three structures and crews are preparing the subgrade for a working platform to set new stormwater management structures. In the northern work zone, crews are clearing and placing a stream diversion at two structures and the newly named road, Terrapin Run. There will be minimal night work scheduled only to relocate cranes.

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. 

SHA will be trimming brush and trees and installing additional signage along MD 99 over the summer to mitigate sight distance isssues at the existing stop-controlled intersections.
