Watch "City Issues" program about the project: 

The Project

The Monocacy Boulevard, Central Section Phase 2 project extends from the intersection of Monocacy Boulevard and Gas House Pike to the intersection of Monocacy Boulevard and Schifferstadt Boulevard. The project includes the construction of approximately 3,550 linear feet of a four-lane roadway inclusive of a new two-lane bridge and the rehabilitation of the existing two-lane bridge over the Monocacy River. The project also includes a new traffic signal at the intersection of Monocacy Boulevard and Gas House Pike. The road will have much the same character as Schifferstadt Boulevard, and the most recent portion of Monocacy Boulevard, with sidewalks, a shared use path, landscaped medians, etc.

***Update - May 2019

The project to realign and widen Monocacy Boulevard has been delayed by exceptionally wet weather.

The reopening of Monocacy Boulevard between Gas House Pike and Schifferstadt Boulevard/ East Church Street is now estimated to occur in late summer of 2019.

The City appreciates the public’s patience and is aware of the inconvenience this has created since the road closed in fall of 2017. This major transportation project has been planned for a decade to improve traffic flow from the southeast to northeast areas of the City, providing alternates to northbound U.S. 15.

Update - February 2019

Scheduled Substantial Completion: Summer 2019 (Revised because of weather)

Update - November 2018

Structure S1 New Monocacy River Bridge: deck is complete, Contractor preparing to install sidewalk (10-foot wide shared-use sidewalk) and parapets 

Structure S2 Existing Monocacy River Bridge: Contractor began rehabilitation of the old Monocacy River Bridge in early October. Rehabilitation includes spall repair on piers, abutments, and deck; painting existing structural steel; modifying the north sidewalk from 3-foot width to 5 ½-foot width.

Structure S3 Carroll Creek Retaining Wall: nearing completion, final segment of wall will be complete after 36-inch sewer is installed along Monocacy Boulevard and across Carroll Creek.

Park Branch Culverts: Contractor is working to complete removal of existing the installation of the 5- to 8-foot diameter culvert pipes that will convey the stormwater through Abraham Faw Run/Park Branch from the north side of Monocacy Boulevard to the south side toward the Monocacy River. Approximately three quarters of the culvert length is complete (approximately 175 of the 235 feet each are installed). The rain and flooding of the Monocacy River and Carroll Creek have made this a very challenging activity.

Update - October 2018

State Highway Administration Progress                                                                                              

In October, the State Highway Administration (SHA) completely closed the Hayward Road connection to US 15 and opened the new southbound US 15 on/off ramps. SHA is currently finishing the remaining work on US 15 main line (milling, paving, marking, etc.), which is expected to be completed in November, weather permitting.

City Progress                                                                                                                                           

The City of Frederick DPW also recently completed work at the intersection of Thomas Johnson (TJ) Drive and Hayward Road to convert the intersection from a three-way stop to an all-way stop controlled intersection. The only change that was implemented as part of this work at the intersection is an additional “stop” sign placed on the westbound Hayward Road approach to the intersection.


Drivers are cautioned to pay attention to the new traffic patterns in the area, come to a complete stop at stop signs, and observe posted speed limits (25 mph). Please note that detour signs are provided on northbound TJ Drive and eastbound Hayward Road at the intersection to direct northbound TJ Drive drivers to continue north on TJ Drive to access the new US 15 interchange/ramps.

Update - January 2018:Steel will be erected for the new bridge in March. This bridge will carry two lanes of eastbound traffic when the road is opened.

Washington Gas, Potomac Edison and Verizon will begin major relocations of their utilities in the next two months to accommodate the new roadway alignment. The old bridge will be rehabilitated to include pedestrian safety fencing, lighting, and a widened sidewalk.Traffic concerns:

The City understands the closure of Monocacy Boulevard creates some commuting challenges. The City's Engineering Department, Police and Mayor will be continuously monitoring traffic along the various detour routes and will evaluate potential modifications to traffic controls to improve the movement along those corridors.

MD 26We are also coordinating with Maryland State Highway Administration and Frederick County, as needed, to address issues, since MD 26 is a State road, and Gas House Pike east of ALDI is within the County.

We believe the temporary inconvenience of Monocacy's closure will be well rewarded once the improved Monocacy Boulevard opens. Monitor this page for the latest alternate route recommendations.

What the Monocacy Boulevard project accomplishes:

  • Make Monocacy Boulevard straighter, safer, less likely to flood and able to serve four lanes of traffic - two in each direction
  • Construction of a new bridge over the Monocacy River, and rehabilitation of the existing bridge, providing improved accommodations for pedestrians and bicyclists
  • Installation of a traffic signal at the intersection of Monocacy Boulevard and Gas House Pike
  • Ease access to/from North/East side of City
  • Why Monocacy Boulevard must be closed now:

    The project requires demolishing the existing road in order to construct the new four-lane road, along the same general alignment, but at a higher elevation.

    Because the work follows the same general alignment of the existing road and the roadway will be raised, there is no room within the narrow corridor to shift traffic to one side or the other during demolition of the existing road or construction of the new road until construction is nearly complete.

    July 2018: US 15/MD 26 Construction

    The Maryland State Highway Administration manages the U.S. 15 construction and timeline. Monday, July 23, the Maryland State Highway Administration will open the Monocacy Boulevard bridge over U.S. 15 and a new ramp, which are part of the U.S. 15 (Catoctin Mountain Highway) /Monocacy Boulevard interchange project. Information about that and other state highway projects is on the SHA projects page.
