The final section of MD 404 is a design-build project to construct the remaining 9.2 miles between US 50 and MD 309 (5.8 miles) and west of Hillsboro Road to east of Holly Road (3.4 miles). Schedule is as follows:

Summer and Fall 2016 Project site clearing, utility relocation installations, and construction of the new MD 404 will be underway. The existing MD 404 roadway (two lanes, one way each direction) and intersection movements will be maintained.
Fall 2016/Winter 2017 Starting in September/October 2016, crews will install pipe culverts under the road. At times traffic will be reduced to one lane in both directions using flagging operations.
Winter 2017 Crews will begin installation of box culverts and large pipe culverts under the road. Traffic (two lanes, one way in each direction) will be shifted onto the newly constructed MD 404 roadway from ½ mile east of Owens Road to Fox Meadow Road and also from Log Cabin Road to Holly Road. Existing intersection movements will be maintained.
Late 2017 Substantial project completion — open to traffic
Spring 2018 Project completion
