US 0015 CATOCTIN MOUNTAIN HIGHWAY MONOCACY BOULEVARD INTERCHANGE

When will this impact me?

Project Name:

US 15, Catoctin Mountain Highway

Location of Project:

MONOCACY BOULEVARD INTERCHANGE

Description:

Design of a grade-separated interchange at Monocacy Boulevard including a Park-and-Ride lot. This project will include appropriate bicycle and pedestrian facilities. (BRAC Related)

Scope:

The I-270/US 15 Multi-Modal Corridor Study, initiated in the mid-1990’s, is considering capacity and safety improvements along I-270 and US 15, from Gaithersburg through the City of Frederick and northward to Biggs Ford Road. The I-270/US15 Multi-Modal Corridor Study’s 2002 Draft Environmental Impact Statement (DEIS) included a diamond interchange at the US 15/Monocacy Boulevard intersection to improve safety conditions along US 15 and provide an east-west connection for vehicles, bicyclists, and pedestrians. This proposed interchange was also presented at the
I-270/US 15 public hearings in 2002. In November 2005, the Federal Highway Administration (FHWA) granted approval for the State Highway Administration (SHA) to conduct a separate study for the Monocacy Boulevard area, breaking it out from the larger I-270/US 15 Multi-Modal Corridor Study.

This study is nearly complete after selecting Alternative 2 - Option 1 described below. The proposed diamond interchange has entered the design phase which is expected to be complete in spring 2012.

What is under study:

The following is the selected alternative that has entered final design:

Alternative 2 – Option 1: (Chosen as the Preferred Alternative). Proposes a grade-separated diamond interchange as shown in the I-270/US 15 DEIS and at the public hearings. Monocacy Boulevard is extended west of US 15 to connect with Thomas Johnson Drive. The interchange includes the bridge structure, ramps with acceleration/deceleration lanes along US 15, and signalized intersections on Monocacy Boulevard at the on/off ramps access locations. The access from Hayward Road to US 15 will be closed and modified as a cul-de-sac.
