Interstate 695 Maryland
A heavily traveled freeway, Interstate 695 encircles Baltimore as both a busy commuter route and a truck bypass. Milepost 0 is located at the double leaf bascule on the Curtis Creek Bridges at Hawkins Point in Baltimore city. The Baltimore Beltway uses a sequential exit numbering system due to the close proximity of interchanges.
The entire 51.57 mile1 long Baltimore Beltway is signed as Interstate 695. The Maryland Department of Transportation (MDT) 2016 Highway Location Reference (HLR) logs attribute 29.17 miles to IS 695 in Baltimore County, including the 1.52 mile overlap with IS 83, and 2.92 miles in Anne Arundel County. This figure represents the beltway from Interstate 97 near mile marker 3 clockwise to I-95 at Rossville (Exit 33). MD 695 extends the beltway 11.366 miles south from I-95 to the Baltimore city line past mile marker 48. MD 695 resumes along the Beltway another 2.48 miles west from the city line, from a point 0.16 miles ahead of MD 710, to Exit 4 with I-97 south. 3.34 miles of I-695 fall within the city of Baltimore, including the 1.6 mile long Francis Scott Key Bridge. The toll bridge across the Patapsco River is maintained by the Maryland Transportation Authority (MDTA).
Began as a county project, the Baltimore beltway originated in planning as early as 1949. Taken over by the state in 1953 and added to the Interstate system by 1956, the beltway was three quarters complete by 1962. Portions of the Windlass and Patapsco Freeway projects were incorporated into the southeastern quadrant by 1974.2

I-695 Annual Average Daily Traffic (AADT)
The Baltimore Beltway was completed north from Maryland 2 in Anne Arundel County to U.S. 40 (Pulaski Highway) east of Baltimore in 1962. The next portion to open was the Southeast Freeway between Pulaski Highway and Maryland 150 (Eastern Boulevard) in 1972.2 This section was later dropped as part of the Beltway mainline, with I-695 shifting westward along portions of the Winlass and Patapsco Freeways.
The Baltimore Beltway was vastly complete in 1976 with the exception of the Francis Scott Key Bridge and its approaches, which opened a year later. Signs for the beltway displaying Maryland 695 were later replaced with tri-color Interstate markers for continuity purposes.
The official route of Interstate 695 ran along the northern portion of the Baltimore Beltway. As approved by AASHTO on November 15, 1975, the Interstate portion was lengthened from a point south of Baltimore to the Anne Arundel Expressway (Maryland 10). The Francis Scott Key Bridge was the final segment built along the overall beltway. Discussion for a second Patapsco River crossing in Baltimore started in the early 1960s as a solution to traffic congestion along the Baltimore Harbor Tunnel (Interstate 895). A tunnel was proposed, and bids for construction were accepted on July 30, 1970. However due to substantial costs, officials shifted plans from a tunnel to a four-lane bridge.3
Construction on the Francis Scott Key Bridge commenced in 1972. Costing $60.3 million, the 10.9 mile project included the steel arch-shaped continuous through truss bridge over the Patapsco River, the 0.64-mile long dual-span drawbridge over Curtis Creek, and the 0.74-mile long spans over Bear Creek, east of Coffin Point. Topping out at 185 feet, the Francis Scott Key Bridge opened to traffic on March 23, 1977.3
The Francis Scott Key Bridge approaches were constructed with two overall lanes. The western section was expanded a short time after the span opened. The eastern segment through the Sparrows Point industrial area was not expanded to four lanes until November 1999.2
Expansion plans underway in the early 2000s estimated $800 million in funds needed for widening two sections of the Baltimore Beltway. Options considered including adding Express Toll or High Occupancy Toll (HO/T) lanes with variable rates based upon traffic congestion and time of day. Sections outlined for widening from six to eight lanes included the Beltway north from I-95 at Halethorpe to MD 122 (Security Boulevard) at Woodlawn and I-695 east from I-83 near Towson to I-95 near Overlea.4 HO/T lanes were not implemented along the Beltway at that time.
Construction in the mid-2000s widened the northern portion of the beltway between I-795 (Northwest Expressway) and Interstate 83 to eight lanes and added sound barriers. Other expansion projects along the Beltway in 2004 included reconstructing the Liberty Road interchange (Exit 18) and adding a southbound lane between Frederick Road (Exit 13) and Interstate 95 (Exit 11). Maryland 43 (White Marsh Boulevard), which provides an alternate route from I-695 east to I-95 north at White Marsh, was extended to Eastern Avenue (Maryland 150) by 2006.4
