County Route 111 (CR 111) is a north–south expressway in Suffolk County, New York, in the United States. It runs northwest and southeast from New York State Route 27 (NY 27) at exit 62 near Eastport to Interstate 495 (I-495) at exit 70 in Manorville. It serves as a connecting route between central Long Island and the Hamptons. The road is known as Captain Daniel Roe Highway, for Captain Daniel Roe (1740–1820) of Selden, who served in the French and Indian War and was a captain in the Revolutionary War. Within Manorville, the road is also known as Eastport Manor Road. It also appears on maps as Port Jefferson-Westhampton Road, for the communities in which the route was originally intended to have its north and south endpoints in.

Route description

CR 111 begins at an incomplete interchange with NY 27. Currently designed as a diamond interchange with collector/distributor roads, the intersection was originally planned as a cloverleaf with the service roads. The route heads northwest through rural areas as a four-lane expressway with a wide grassy median and a speed limit with 55 miles per hour (89 km/h).

The highway intersects with CR 51 (East Moriches–Riverhead Road) by way of a half-diamond interchange, with an exit ramp from CR 111 south and an entrance ramp to CR 111 north. Following this junction, it crosses over a long dirt road named Toppings Path.

As CR 111 advances northwest of Toppings Path, it approaches a slightly more residential area of Manorville to the west and Manorville Hills County Park to the east. The southbound lanes feature a right-in/right-out interchange with Gordon Street, leading to Eastport–Manor Road (formerly CR 55). Subsequently, CR 111 meets the northern end of Eastport–Manor Road at a signalized intersection with the southbound lanes.

North of this intersection, CR 111 transitions from a divided expressway to an at-grade expressway with a lower speed of 45 miles per hour (72 km/h), proceeding via the original alignment of Eastport–Manor Road for the duration of the route.

Upon encountering a pair of traffic signals with Halsey Manor Road and Chapman Boulevard, CR 111 enters a more commercial area, housing two main shopping centers anchored by a King Kullen supermarket and CVS Pharmacy. Further northwest, CR 111 intersects with exit 70 of Interstate 495 (Long Island Expressway), a diamond interchange with traffic signals.

CR 111 concludes at the northern signal with I-495 west. However, Eastport–Manor Road extends for a short distance as a two-lane, 30-mile-per-hour (48 km/h) street.

History

The route was first planned by Suffolk County in the 1960s to serve as a link between major locations on the northern and southern shores. However, the only part of this route to ever be constructed is a small section between Eastport and Manorville. The initial plans were cancelled due to county budget cuts and environmental opposition to constructing a highway through the Pine Barrens region.

Completed segment

The current CR 111 opened to traffic in early 1975. It runs from the Long Island Expressway (I-495) in Manorville to Sunrise Highway (NY-27) in Eastport. It is a major link in the road network on Long Island. This is due to how it connects NY-27 to I-495, given the fact that it provides motorists with a link between the Hamptons and New York City, in addition to its suburbs in Nassau County and western Suffolk.

Unbuilt segments

New York State Route 113
Port Jefferson–Westhampton Beach Road
Location	Port Jefferson Station–Westhampton Beach

As suggested by its name, Port Jefferson–Westhampton Beach Road (CR 111) was intended to travel between Port Jefferson and Westhampton Beach, and connect to several highways via interchanges: the east end of CR 90, the west end of the cancelled extension of CR 105, and a cancelled northern extension of CR 55 (Eastport–Manor Road). As originally planned, CR 111 would have been a 21-mile (34 km) highway extending from NY 25A and NY 347 in Port Jefferson Station to Montauk Highway in Westhampton Beach. In addition to being a convenient travel route, the routing would have been strategic, as well, as it was intentionally planned as a link between the deep-water port of Port Jefferson Harbor and the Calverton Naval Weapons Reserve Plant in Calverton to the former Suffolk County AFB in Westhampton Beach.

As per the 1970 Nassau-Suffolk Regional Planning Board recommendation, CR 111 would be transferred to the New York State Department of Transportation (NYSDOT). This would have resulted in CR 111 being renamed as New York State Route 113.

Proposed routing

Heading southeast from NY 25A and NY 347, CR 111 was to replace Canal Road. It would then have interchanges with CR 83 (Patchogue–Mount Sinai Road) and Coram–Mount Sinai Road, where it would have broken away from Canal Road and run along its south side. CR 111 would then replace Whiskey Road west of its intersection with Miller Place–Middle Island Road and Coram–Sweezeytown Road. It would break away from Whiskey Road east of Middle Island Boulevard, cross over Miller Place–Yaphank Road, and reunite with Whiskey Road again until the proposed interchange with CR 21 (Rocky Point–Yaphank Road). CR 111 would then shift to the northeast corner of CR 21 and Whiskey Road, running parallel with Whiskey Road until north of the intersection with Currans Road, where it would cross over Whiskey Road and remain along its south side until its terminus at CR 46 (William Floyd Parkway) in Ridge.

East of William Floyd Parkway, CR 111 was intended to have an interchange and then curve south through Brookhaven State Park on land once formerly owned by the Brookhaven National Laboratory. After the interchange with NY 25, it would shift eastward along the northern border of Brookhaven Lab, crossing the Robert Cushman Murphy County Park twice. In between this Suffolk County Preserve area, it would run through the grounds of the Grumman Calverton Naval Weapons Industrial Reserve Plant. It was to then follow along Wading River–Center Moriches Road (former CR 25) before heading south again toward the Peconic River. The road would join its existing section on the northeast corner of the westbound service road on the Long Island Expressway (I-495) at exit 70.

Continuing southeast from the existing highway's southeastern end at the interchange with NY 27, CR 111 was to run southeast across the Pine Barrens. It would run roughly parallel to CR 71 (Old Country Road) before intersecting with it at the Montauk Branch of the Long Island Rail Road. It was then intended to replace CR 71 as it crossed Montauk Highway and headed through the village of Westhampton Beach towards the Atlantic Ocean coastline.

Safety improvements

Local residents and political leaders have made considerable efforts to enhance the safety conditions on County Route 111 (CR 111), particularly during peak travel times in the summer season. CR 111 acts as a significant conduit for travelers moving between the Long Island Expressway (I-495) and NY 27, often resulting in traffic congestion during Friday and Sunday afternoons. This issue is particularly noticeable in Manorville, where CR 111 plays a vital role in linking local services and stores.

Concerns have escalated due to an increase in the accident rate on the road, prompting attention from Suffolk County. In response, various safety measures have been proposed and implemented. Following the lobbying efforts of local representative Edward Romaine, the county undertook comprehensive traffic studies. As a temporary measure, two new traffic lights were installed at the offramps of the Long Island Expressway to manage the traffic flow.

Upon completion of the traffic study, more long-term solutions are expected to be implemented, which may include additional or better-coordinated traffic signals, traffic calming devices, and a potential reduction in the speed limit through Manorville's hamlet center.

In 2023, further safety improvements were announced for State Route 111 between Suffolk Avenue and the Long Island Expressway in the Town of Islip. These improvements are part of a larger $157 million investment in pavement renewal projects on Long Island.
