Interstate 97


Interstate 97 is the shortest two-digit Interstate in the 48 contiguous states. With only 17 miles, I-97 also lies wholly within Anne Arundel County. It generally serves as a commuter route between Baltimore and Annapolis.

Two freeways make up the alignment of Interstate 97: the Glen Burnie Bypass (former Maryland 3) to the north and the former eastern extent of Maryland 32 to the south. The north end includes a direct connection with Interstate 895 Spur to the Baltimore Harbor Tunnel.

Parallel U.S. Routes

Interstate 97 replaced portions of Maryland 3, which was the northernmost extent of U.S. 301 until 1960, when it was redirected to end at Glasgow, Delaware.


During the 1970s, Maryland proposed routes for both Interstate 68 and Interstate 97 in the Annapolis area. I-68 was planned for U.S. 50 between the Capital Beltway and a point west of Annapolis. I-97 was projected for a north-south route from the end of I-68 to the Baltimore Beltway. In addition, the U.S. 50 freeway east from I-68 and I-97 to the present end of I-595, was incorporated as Interstate 197. Interstate 297 was also introduced as the replacement for Maryland 3, from U.S. 50 and 301 north to Maryland 32. AASHTO approved I-97 north of U.S. 50 and I-297 on November 15, 1975. Conditional approval was granted to I-197 and to the I-68 segment as an extension of I-97.

Further changes from Maryland regarding Interstate 97 were submitted to AASHTO on October 3, 1981. Again Interstate 68 was proposed in place of I-97 for the U.S. 50 freeway between the Capital Beltway and the previously referenced point west of Annapolis. The I-197 spur east from there to Maryland 70 was then proposed as Interstate 168. These changes were approved AASHTO by subject to FHWA concurrence. Interstate 197 was never signed, Interstate 297 was never built, and by 1989, both proposed I-68 and 168 were instead renumbered as Interstate 595.

The Glen Burnie Bypass was constructed during the 1960s as a new alignment for Maryland 3. This resulted in the designation of Maryland 3 Business, which still runs east of I-97 along Crain Highway today. The freeway south from the Maryland 3 and 32 intersection to U.S. 50 & 301 opened to traffic in 19891

Construction for Interstate 97 between Dorrs Corner (Maryland 178) and New Cut Road (Exit 12) ran from 1988 to February 13, 1991. The $31-million project wrapped up with the opening of the new northbound lanes through the Millersville area.2

Portions of old Maryland 3 were converted into an east side frontage road (Veterans Highway) along the newly opened Interstate 97 in 1991.2 A traffic light on I-97 at Old Mill Road remained in operation along this stretch until July 2, 1991, as work to convert Veterans Highway to two-way traffic was delayed by six weeks.3

Southern Terminus - Interstate 595 and U.S. 50/301 - Annapolis, Maryland
Perspective from Interstate 97 south
Interstate 97 southbound at Junction Hidden Interstate 595 and U.S. 50/301. This marks the southern terminus of Interstate 97. Notably, there are empty brackets for an exit tab on the right-hand sign. Photo taken 06/00.
Perspective from Interstate 595/U.S. 50 west/U.S. 301 south
U.S. 50 west and U.S. 301 south for miles west of the Chesapeake Bay Bridge see this signage for Baltimore area traffic interests. This is the first indication of the southern terminus of Interstate 97. Photo taken 06/02/03.
Interstate 595/U.S. 50 west and U.S. 301 southbound, one mile east of Interstate 97/Exit 21. Note that this sign bridge includes panels also for Maryland 665/Exit 22 and Maryland 450/Exit 23B. With that stated, Exit 21 for Interstate 97 departs before Exit 22 for Maryland 665 even though this is facing west. This is because the Interstate 97 beginning from this direction parallels Interstate 595 for a distance before turning northward. Photo taken 06/02/03.
A hairpin turn composes Exit 23 for adjacent Maryland 450 to Crownsville. U.S. 50/301 see several of these types of off-ramps to the adjacent frontage roads. Interstate 97's departure is in one half mile. Photo taken 06/02/03.
Interstate 595/U.S. 50/301 maintain six lanes through the southern terminus of Interstate 97 interchange. This westbound photograph looks at the northbound beginning of the Annapolis to Baltimore freeway. Photo taken 06/02/03.

The aforementioned parallel alignment of Interstate 97 north alongside Interstate 595/U.S. 50 west and U.S. 301 south. Return access to the westbound freeway is granted due to the merge of Maryland 665/Aris T. Allen Boulevard onto the Interstate 97 roadway. In effect, this portion of Interstate 97 acts as a collector distributor roadway. Photo taken 06/02/03.
Interstate 97 turns to the northwest than north while Maryland 665 traffic wishing to enter Interstate 595/U.S. 50 west and U.S. 301 south depart to the left. Washington D.C. is 20 miles to the west. Photo taken 06/02/03.

Two lanes of Interstate 97 are allocated for Interstate 695 westbound to Baltimore and the northern suburb of Towson. Traffic taking Spur Interstate 895 northbound will default onto Interstate 895 northbound through the Harbor Tunnel. Therefore traffic headed to downtown Baltimore is advised to take Interstate 695 west to either Interstate 95 north or Maryland 295/Baltimore-Washington Parkway north. Photo taken 06/02/03.
Traffic utilizing Exit 17B will reach the tolled Francis Scott Key Bridge ($1 per passenger vehicle) in five miles.
