This $85M design-build project, awarded by the Maryland State Highway Administration, includes construction of a four-lane divided highway for six miles, with two lanes in each direction. It also involves replacing three existing bridge structures and box and pipe culverts, paving of new roadways, rehabilitation to existing roadways, new traffic signage, utility relocations and stormwater management (SWM).
Construction on the project began in June 2019 and is scheduled to be complete by summer 2022.

- A one-mile, permanent access road was built parallel to MD 32 for relocated utilities and to provide safer access for properties previously having a direct access driveway.
- SWM includes over 10 miles of roadside grass and bioswale facilities along with 15 SWM ponds.
- Scheduling and coordination to minimize impacts to traveling public and Howard County school.
