text: new york state route 429 new york state route 429 ( ny 429 ) is a north – south state highway located entirely within niagara county , new york , in the united states . it extends for 12 . 16 miles ( 19 . 57 km ) from an intersection with ny 265 and ny 384 in north tonawanda to a junction with ny 104 ( ridge road ) on the border between the towns of cambria and lewiston . although it is relatively minor in length , the route is regionally important nonetheless as it connects north tonawanda to some of the county 's interior regions . about midway between north tonawanda and ridge road , ny 429 serves the hamlet of sanborn , where it briefly overlaps with ny 31 . at pekin , a community situated between sanborn and ny 104 , ny 429 descends the niagara escarpment . the sanborn – ridge road segment of modern ny 429 was originally designated as part of route 30 , an unsigned legislative route , in 1908 . in the mid - 1920s , the portion of route 30 west of rochester became part of the signed ny 31 ; however , ny 31 was realigned in the late 1920s to follow ridge road west from cambria to the village of lewiston . ny 31 's former alignment from niagara falls to ridge road via sanborn became new york state route 31a at this time . ny 31a was eliminated c . 1935 as part of the establishment of u.s. route 104 ( us 104 ) . the portion of its former routing north of sanborn became part of the new ny 429 , which was assigned to its current alignment upon assignment . route description ny 429 begins on the banks of the niagara river at a junction with ny 265 and ny 384 in downtown north tonawanda . the route heads east as wheatfield street , crossing the csx transportation - owned niagara subdivision at a grade crossing that separates an industrialized block of the street from more residential sections to the east . after three blocks , ny 429 turns onto oliver street and follows it northwestward through residential and industrial portions of the city , paralleling ny 265 and ny 384 for 1 . 5 miles ( 2 . 4 km ) to a junction with ward road . oliver street and ward road merge here , and the combined street takes on the ward road name as it proceeds due northward through the solely residential northern portion of north tonawanda . ny 429 exits the city near a junction with road , at which point maintenance of the route shifts from the city to the new york state department of transportation ( nysdot ) . now in the town of wheatfield , ny 429 heads across populated but less developed areas on its way to a junction with us 62 . north of this point , the closely spaced homes gradually give way to more isolated houses and , eventually , rural farmland . it continues on a north – south line to the town of lewiston and the hamlet of sanborn , located adjacent to the lewiston – cambria town line . in the small but developed community , ny 429 follows buffalo street past three blocks of homes to a junction with ny 31 ( saunders settlement road ) . buffalo street ends here ; however , ny 429 joins ny 31 for two blocks east to townline road , a north – south highway delimiting the boundary between lewiston and cambria . ny 429 continues north on townline road , passing the sprawling main campus of niagara county community college , a stark departure from the rural fields that ny 429 traversed in wheatfield . past the college , ny 429 follows the lewiston – cambria town line for the rest of its length . in terms of elevation , it reaches a crest of 644 feet ( 196 m ) at upper mountain road in pekin before it begins to descend the niagara escarpment , a beach ridge that further west led to the formation of niagara falls eons ago . here , on clear enough days , a wide panorama can be seen of the entire northern half of the county and lake ontario . after descending 100 feet ( 30 m ) , it crosses a narrow plateau containing lower mountain road . another 150 - foot ( 46 m ) drop follows , and ny 429 ends shortly afterward at a junction with ny 104 ( ridge road ) located 392 feet ( 119 m ) above sea level — a 252 - foot ( 77 m ) descent from pekin . during this final , mostly undeveloped stretch , ny 429 passes the buffalo diocese 's immaculate conception catholic church . history the portion of modern ny 429 north of sanborn was originally designated as part of route 30 , an unsigned legislative route , by the new york state legislature in 1908 . route 30 entered sanborn from the west on what is now ny 31 and followed current ny 429 north to ridge road , where it turned east toward rochester . all of legislative route 30 west of rochester became part of ny 31 in the mid - 1920s , while the remainder of what is now ny 429 outside of north tonawanda was taken over by the state of new york by 1926 . in the late 1920s , ny 31 was realigned between niagara falls and the lewiston – cambria town line to follow ridge road west to the village of lewiston . its former routing to niagara falls via sanborn became ny 31a . in the 1930 renumbering of state highways in new york , the niagara falls – sanborn leg of ny 31a became part of a realigned ny 3 , which had followed modern ny 425 from north tonawanda to saunders settlement road prior to the renumbering . despite this fact , ny 31a continued to extend west to niagara falls , creating an overlap with the cross - state ny 3 . the overlap remained in place until c . 1935 when us 104 was assigned across upstate new york . west of rochester , it replaced ny 31 , which was shifted southward to follow all of ny 3 from niagara falls to rochester . ny 31a , meanwhile , was eliminated and partially replaced with ny 429 , a new route that continued south from sanborn to north tonawanda via ward road and oliver and wheatfield streets . ny 429 has not been substantially altered since that time . major intersections the entire route is in niagara county .
