as sunrise highway upgraded during 1970s , 1980s many interchanges redesigned , replaced. original interchange robert moses causeway in west islip had 2 parkway-style arch bridges on 2 lanes of ny 27. when service roads built in western islip township between 1969 , 1972, parkway-style bridges added them well. interchanges @ fifth ave , brentwood road in bay shore had parkway-style arch bridges , cloverleafs. when service roads added, parkway-style bridges removed , replaced modern structures exist today , original cloverleafs modified align new service roads.

as interchanges west, islip avenue (ny 111) , carleton avenue (cr 17) in islip terrace had parkway-style bridges crossing on sunrise highway. however, islip ave had partial clover leaf on west side of bridge. eastern side of bridge used side streets access, did both sides of carleton ave bridge. section of sunrise highway wasn t divided. since 1983, both areas have more modern bridges on service roads, , old cross streets connect service roads or other side roads instead. islip avenue connects ny 27 @ exit 45 while carleton avenue meets sunrise highway @ exit 46.

proposed interchanges , crossings

besides replacement of interchanges in western suffolk county, sunrise highway has had proposed interchanges , crossings either never built, or built according alternate design specifications.

in north lindenhurst area, plans construct cloverleaf interchange cr 2 (straight path) in copiague have existed time. in recent years, planners have realized such interchange close cloverleafs cr 47 (great neck road) west , cr 3 (wellwood road) east. further complicate matters, widened cr 28 extended sunrise highway near straight path intersection in late-1980s. date, no interchange has been built area.

the oakdale merge convergence of sunrise highway , montauk highway between great river , oakdale abutting southern edge of connetquot river state park. montauk highway predates sunrise highway in area. when sunrise highway extended east of amityville in 1940, terminated @ montauk highway s entrance connetquot river state park.

in 1953, sunrise highway extended east patchogue; 0.5 mi (0.80 km) overlap of ny 27 , ny 27a created, at-grade intersections connecting highways. segment of alignment remains south of eastern interchange.

ny 27a truncated east of overlap in 1972. plans upgrade interchange have existed since creation.

during early-1960s, suffolk county department of public works considered designating county highway connect nicolls road in lake grove through long island macarthur airport, on east end of merge. 1981, new york state department of transportation planned add service roads , proper interchange @ both ends of merge. pressure environmental groups seeking avoid damaging parkland stalled construction. nysdot reconstructed sunrise highway in eastern islip township freeway during 1990s, resulting in present configuration.

the entrance connetquot river park remained at-grade intersection, accessible westbound lane. former segments of montauk highway exist on both sides of interchange, , sections of both roads converted fishing areas owned new york state department of environmental conservation. numerous accidents occurred @ east end of merge, resulting in reconstruction in 1999. new off-ramp service road pond road built, resulting in renumbering of exit 47 exit 46a.

while none of interchanges north of patchogue built until 1988 1993, new york state department of transportation (nysdot) had known need them, , had planned them decades before eventual construction. example, waverly avenue (cr 19) proposed cloverleaf interchange. today, exit 52 cr 19 diamond interchange instead. north ocean avenue (cr 83) proposed accessible via connecting ramps side streets including austin street along eastbound lane , sinn street along westbound lane. today, exit 53a half-diamond interchange while austin street , howard street dead end streets, , sinn street never reached north ocean avenue.

maple avenue had crossed median on ny 27 between north ocean avenue , ny 112 until 1975. road have been used connecting ramp both roads. today, north section intersects westbound service road, while south section converted dead end street north of austin street. ny 112 proposed accessible via connecting ramps side streets such franklin street along eastbound lane , extension of sinn street along westbound lane.

sinn street acquired nysdot east of ny 112 in early-1960s, , gradually abandoned. today, exit 53 diamond interchange, , sinn street, austin street, , franklin street dead-end streets. there proposals connect washington avenue , phyllis drive via ramps side streets such franklin street along eastbound lane, , extension of sinn street along westbound lane.

phyllis drive once part of ny 27 until sunrise highway extended eastport in 1957. today, both roads accessible via service roads. residents waiting potential pedestrian bridge connecting 2 ends of washington avenue.
