CT 100

4.40 miles; from US 1 to Route 80 in East Haven. The south end is a little tricky: starting at US 1 just west of Lake Saltonstall, Route 100 northbound continues west along Main Street, crossing Route 142. Turning right on High Street, Route 100 continues north, overpassing US 1 and underpassing I-95.

History:

Route 142 absorbed today's Route 337; scan from 1965 official map
From 1963 to about 1970, Route 100 extended south to end at an extended Route 142. Scan from 1965 official state highway map.
In the 1920s, the state's internal highway numbers began with 101, so there was no state highway 100.

In 1932, the first Route 100 was created along what is now Route 39 between New Fairfield center (at Route 37) and Danbury center.

In 1933 or 1934, the first Route 100 was decomissioned and divided up between an extended Route 39 (Ball Pond Rd and Milltown Rd into New York State) and a new Route 37A (the remainder of Ball Pond Rd and Clapboard Ridge Rd to Danbury).

In 1935, the modern Route 100 was commissioned in East Haven, from US 1 to Route 80, a length of 3.92 miles. In 1943 or 1944, it was extended south to Dodge Avenue, at the entrance to Tweed-New Haven airport, for a length of 4.69 miles.

Sometime in the 1950s, Route 100 was redefined to turn east at Main Street to end at Route 142.

In 1963, Route 142 was extended westward along today's Route 337 into New Haven. Route 100 was extended southward along Hemingway Ave. and Short Beach Rd. to end at Route 142.

In 1970 or 1971, however, the state reversed its change to Route 142, leading to today's configuration for that road and Route 100.

In 1999, Route 100's intersection with Route 80 was relocated slightly, and Route 100's length decreased by 0.04 mile.

 
CT 101

19 miles; from US 44 in Pomfret to US 6 in North Scituate, Rhode Island. One of the primary east-west routes to Providence. 9.46 miles in Connecticut.

History:

In a way, Route 101 survived the Great Renumbering of 1932, where few others did.

In the 1920s, State Highway 101 had the following route in Connecticut:

  • today's Route 198, from US 6 in Chaplin to US 44 in Ashford
  • today's US 44, easterly through Pomfret and Putnam to the Rhode Island state line

At the time, present-day Route 101 between Routes 169 and 12 was called SH 137; between Route 12 and Rhode Island, SH 139.

On Jan. 1, 1932, the "Great Renumbering" took place, and Route 101 was extended nearly all the way across Connecticut, totaling more than 90 miles. Its new route was:

  • today's US 44, from US 7 in Canaan to US 5 in East Hartford
  • Silver Lane and Spencer Street (today's SR 502) from East Hartford to Manchester
  • today's US 44 from Manchester to the Rhode Island state line
At this time, present-day Route 101 was called state route 202.

In 1935, US 44 and US 202 were commissioned. US 44 took over all of existing Route 101 in the state. Nearby state route 202, its number displaced by US 202, became the new Route 101.

Route 101 might have been intended for a highway in New Fairfield; a 1934 report to the highway commissioner mentions an investigation of Route 101 in that town. However, the 101 numbering was never removed from its Eastern Connecticut roots.

CT 102

3.45 miles; from Route 35 to US 7 in Ridgefield.

History:

In the 1920s, State Highway 102 followed today's Route 85 from Colchester to New London.

The modern Route 102 was commissioned in 1932, from the 1920s SH 329. It originally extended to the New York state line along Catoonah Street, High Ridge Avenue, Barry Road, and West Mountain Road, for a length of 7.54 miles. The road was straightened in Branchville in 1958, resulting in a length of 7.48 miles.

The 1962 route reclassification called for the section west of Route 35 to be returned to the town; however, that remained under arbitration into the 1970s. The Route 102 designation of that section was dropped on March 1, 1979 and renumbered secret route SR 822: still under state maintenance, but no longer signposted.

CT 103

5.31 miles; from Route 80 in New Haven to US 5/Route 22 in North Haven.

History:

In the 1920s, State Highway 103 followed today's Route 14 from Route 12 into Rhode Island.

Commissioned in 1932, the old Route 103 was a 2.39-mile route entirely within Wilton, leading north from the Norwalk town line to a point 2.13 miles north of Route 33, along Chestnut Hill Road and Hurlbutt Street. In other words, it had two dangling ends (though town roads continued) and only intersected one other highway.

in 1963, the old Route 103 became part of today's Route 53.

The modern Route 103 was promoted from two secret routes on Dec. 24, 1987: SR 720 (north half) and SR 750 (south). Until the late 1960s, the north half was part of US 5A.

 
CT 104

6.82 miles; from Route 137 in Stamford to the New York state line. The road continues across the border as Westchester County Route 3.

History:

In the 1920s, State Highway 104 followed today's Route 17 between Glastonbury Center and today's Route 66 in Portland.

In 1932, Route 104 was commissioned, and followed this route:

  • Bedford Street (and Summer Street?), from US 1 to Long Ridge Road (today's Route 104)
  • Long Ridge Road (today's Route 104) into New York

USGS maps in 1947 and 1951 appear to show Route 104's southern segment shifted from Bedford Street to Summer Street. However, today these streets are an opposing one-way pair; if that was true decades ago, then Route 104 traffic would have used both.

At some point later, Route 137 was extended south along Washington Blvd. to US 1. Route 104's southern end was truncated to Route 137, so now Route 104 extends along Long Ridge Road only.

More:

Does Route 104 perform the noble service of segregating the wealthy from the merely affluent, or old money from new? Hartford Courant columnist Denis Horgan fires this salvo (see "sources"):

Put aside the trifling truth that there is barely a person west of Route 104 who gives a hoot for the rest of Connecticut or who would tell us that our car was on fire in the parking lot or that our necktie was dangling into the soup. Set apart the passing reality that those down in Connecticut's tail consider the remainder of the state to be a congregation of riffraff and field hands.
Ah, class warfare.
