You almost need a full tank

Connecticut's a small state, and most of its highways really don't go very far. Here are the longest state roads (mileage in other states included):

• 10, 262 miles (54.28 in Connecticut)
• 12, 259 miles (54.46)
• 32, 141 miles (54.88)
• 8, 134 miles (67.34)
• 55, 132 miles (2.64)
• 138, 118 miles (17.73)
• 15, 83.53 miles
• 2, 58.03 miles
• 63, 52.57 miles

No reason to live

The shortest signed state routes:

• 125, 1.24 miles
• 182A, 1.29 miles
• 166, 1.62 miles
• 200, 1.87 miles
• 315, 1.95 miles
• 314, 2.04 miles
• 155, 2.22 miles
• 139, 2.36 miles
• 135, 2.58 miles
• 319, 2.83 miles
• 71A, 2.92 miles
• 209, 2.93 miles

To tell you, I'd have to kill you

Longest and shortest secret routes:

• 910, 0.04 miles (about 210 feet)
• 837, 0.05 miles
• (87 others are less than 1/2 mile long)
• 847, 7.46 miles
• 434, 10.15 miles
• 800, 11.83 miles (the old Route 8)

Not a through street

Most routes have both ends at another numbered route. Here are some signed state routes that "dead end" for one reason or another:

• 4, West Hartford: state maintenance ends, Farmington Ave. continues
• 71A, New Britain: state maintenance ends near the hospital
• 176, Newington: state maintenance ends at Hartford city line
• 349, Groton: ends at Avery Point (and even has an "END 349" sign)

Roads with holes

A few state highways have "gaps" – short sections where the road is maintained by the city, not the state.

• 10, Hamden: 0.17-mile northbound section, where the southbound section diverges. Southbound 10 there is officially SR 753.
• 34, New Haven: 1.03-mile eastbound section from Route 10 to the Oak St Connector on-ramp. (The westbound road signed 34 is technically SR 706.)
• 83, Manchester: 0.77 miles, from Charter Oak St (SR 534) to Center St (US 6/44). This is the Main Street section of "classic" downtown Manchester.
• 136, Norwalk: 1.09 miles, between Meadow Road and Washington Street.

Connecticut also has special Routes A and B.

Hey Brother!

Pairs of consecutive state routes that intersect:

• 2 and 3, Glastonbury
• 30 and 31, Vernon
• 31 and 32, Mansfield
• 63 and 64, Middlebury
• 68 and 69, Prospect
• 70 and 71, Meriden

No, we're gonna use it. Just leave it where it is.

These stretches of road were completed years before they opened to traffic:

• Route 25, Trumbull: built in 1975, connected in 1982
• Route 72, Plainville: the 6-lane section, built in 1975, opened in 1980

New route changed, old one did not

Some stretches of former state highway ("Old Route X") did not change names when new Route X changed numbers:

• Lebanon: Old Route 89 along CT 289 (see map) (number changed from 89 to 289 in 1964)
• Harwinton: Old Route 72 along CT 4 (see map) (changed 1963)
• Litchfield: Old Conn. 25 along US 202 (see map) (changed 1974)
• Middletown: Old Route 6A along CT 66 (see map) (changed 1968)
• North Branford: Old State Road 917 along Branford Road, former CT 139A (ConnDOT Map PDF)

The unique, the most/least, and the weird

• SR 800 is the only unsigned route to overlap another numbered route (US 202 in Torrington).
• SR 706 is signed as westbound CT 34 in New Haven.
• SR 753 is signed as southbound CT 10 in Hamden.
• CT 4, 176, and 349 have dead ends (not at another signed route)
• CT 34, 83, and 149 officially go a little further beyond where you think they end (at I-84 and Route 2).
• CT 22, 110, 156, and 218 are all L-shaped, with horizontal and vertical sections nearly equal.
• CT 119 is the only route to have been defined and decommissioned three different times.

Routes the state discarded (or could not)

The 1961 route reclassification plan involved turning over many state routes to local maintenance. The state was able to get rid of some, but not all, as the affected towns pressed for arbitration.

• Got rid of: 105, 118 (Darien), 129, 130, 154A, 156A
• Had to keep: 125, 152, 166, 174, 176, 186, 305, 314
