Route 25 was originally laid out as a toll road known as the Bridgeport and Newtown Turnpike in 1801. The Route 25 designation was assigned in 1932 to the turnpike alignment and additionally extended through New Milford all the way to Torrington. The route was cut back to its modern northern terminus in Brookfield in 1974, with U.S. Route 202 taking over the old alignment. The Bridgeport-Newtown corridor had been planned as an freeway since the 1950s. The modern Route 25 freeway was fully open by 1982.

Route 25 begins at an interchange with Interstate 95 in Bridgeport. For the first 3.8 miles (6.1 km) of the route, it is co-signed with the Route 8 freeway. After the split with Route 8, it continues as its own freeway through the town of Trumbull for another 6.1 miles (9.8 km), providing partial access to the Merritt Parkway (Route 15) along its path through the town. The freeway section ends at the junction with Route 111 on the northern edge of town.

Route 25 continues northward as a surface road following Main Street into Monroe, where it intersects with the northern end of Route 59 in the village of Stepney. Upon entering Newtown, the road becomes known as South Main Street. After intersecting the eastern end of Route 302, it overlaps for 2.7-mile (4.3 km) with U.S. Route 6 northwest from the town center. After turning north onto Hawleyville Road, it intersects I-84 at Exit 9. For the rest of its length, Route 25 is a secondary minor arterial road, crossing Route 133, and ending at U.S. Route 202 in Brookfield.^[2]

Route 25 was originally laid out as a toll road known as the Bridgeport and Newtown Turnpike in 1801 and ran from Bridgeport via Newtown borough to Brookfield Center. In 1848, the north and south ends were made free. In the south, tolls were no longer collected within the city limits of Bridgeport, and in the north, the road north of Newtown borough was made free. In 1886, Fairfield County dissolved all turnpike corporations in its jurisdiction, causing the Bridgeport and Newtown Turnpike to become a public road.

Route 25 was designated along the old turnpike route in the 1932 state highway renumbering.^[1] When originally designated in 1932, Route 25 continued well beyond Brookfield, following Route 133 and Route 67 to New Milford (via Bridgewater), then turning northeast along modern Route 202 before terminating at Route 8 in Torrington. In April 1943, a portion of Routes 25 and 133 swapped alignments. Route 25 now connected to U.S. Route 7 in Brookfield and overlapped it to New Milford, bypassing Bridgewater.^[3] In 1963, Route 25 was extended further eastward to Route 44 in Canton after the relocation of Route 4. In 1974, U.S. Route 202 was relocated and the portion of Route 25 from Brookfield to Canton was taken over by US 202. Route 25 was truncated to its present terminus in Brookfield at this time.^[4]

CTDOT has not announced a renumbering schedule to mile-based exit numbers on Route 25. The "NEW EXIT NUMBERS" shown below are not confirmed, but potential numbers for when the switch to mile-based exit numbers does occur. The entire route is in Fairfield County.
