New Jersey Route 10
Route 10 is a state highway in the northern part of the U.S. state of New Jersey. It runs from an intersection with U.S. Route 46 (US 46) in Roxbury Township, Morris County east to County Route 577 (CR 577)/CR 677 (Prospect Avenue) in West Orange, Essex County. Route 10 is a major route through northern New Jersey that runs through Ledgewood, East Hanover, and Livingston. It is a four-lane highway for most of its length with the exception of the easternmost part of the route. Route 10 features intersections with many major roads including  Route 53 and US 202 in Morris Plains and Interstate 287 (I-287) in Hanover Township. Route 10 was designated in 1927 to run from Jersey City to Dover, following the former Newark and Mount Pleasant Turnpike west of Newark. The route continued east from its present-day routing on current CR 577, Park Avenue, CR 508, and Route 7 to end at US 1/9 at the Tonnele Circle. An alignment of Route 10 farther to the north of its current alignment in Essex County was proposed in 1952; however, it was never constructed with the route being designated to its  present alignment a year later. Since 1953, Route 10 has seen improvements that eliminated the Ledgewood Circle at the western terminus in 1998 and improved safety along the portion of the route in Hanover and East Hanover Townships in the mid-2000s. Route description. Route 10 begins at US 46 in the Ledgewood section of Roxbury Township, Morris County at the former Ledgewood Circle, heading to the southeast on a four-lane divided highway with some jughandles. The road passes by The Shops at Ledgewood Commons, the Roxbury Mall, and many other businesses, also crossing the Dover and Rockaway River Railroad 's High Bridge Branch. The route crosses the Dover and Rockaway River Railroad's Chester Branch before it enters Randolph Township, where the road becomes less commercial in nature and passes Randolph Lake, reaching an interchange with CR 617. Past this interchange, Route 10 crosses over forested Mine Hill. The route crosses CR 513 and passes north of the County College of Morris past that intersection, with suburban development becoming more frequent again. Route 10 widens to six lanes and then runs through the southwestern corner of Denville before heading into the Mt. Tabor section of Parsippany-Troy Hills. The  route then forms the border between Parsippany-Troy Hills to the north and Morris Plains to the south, passing over NJ Transit's Morristown Line before coming to an interchange with Route 53 and crossing US 202. The route fully enters Parsippany-Troy Hills again before crossing into Hanover Township, coming to an interchange with Dryden Way, where the route widens to eight lanes. Past Dryden Way, Route 10 features an interchange with I-287 and narrows to four lanes. The road heads through the Whippany section of Hanover Township, where it has an interchange with CR 511 and crosses the  Morristown and Erie Railway's Whippany Line west of the Whippany Railway Museum. Route 10 enters East Hanover Township at the bridge over Whippany Brook. Along Route 10 in East Hanover, the road passes several businesses. Route 10 crosses the Passaic River into Livingston, Essex County, where it becomes Mt. Pleasant Avenue. The route comes to the Livingston Circle, a realigned traffic circle, in the community of Morehousetown, with CR 508 and CR 609 (Eisenhower Parkway). Past this traffic circle, the divided highway becomes a four-lane undivided road with some businesses and homes along the road. The route crosses  CR 527 and narrows to two lanes a short distance past that intersection. The route enters West Orange at the point it crosses Nance Road. In West Orange, Route 10 ends at the Prospect Avenue intersection where radio station 1560 WFME's studios and 94.7 WXBK's transmitter facilities are located. At this intersection, CR 577 heads east on Mt. Pleasant Avenue and north on Prospect Avenue while CR 677 (signed as CR 577 Spur) heads south on Prospect Avenue. History. Route 10 roughly follows a portion of an old Lenape trail from the Passaic River to Whippany. The Newark  and Mount Pleasant Turnpike was established along the present-day alignment of Route 10 east of Dover on March 12, 1806, existing as a turnpike until before 1833. Route 10 was designated in 1927 to run from Jersey City west to Route 6 (now US 46) west of Dover, passing through Newark. This routing of Route 10 followed its current alignment and ran east along present-day CR 577, Mt. Pleasant Avenue, and Park Avenue to Newark, where it followed CR 508 and Route 7 to US 1/9 at the Tonnele Circle in Jersey City. By 1930, the road's  western terminus had been moved to bypass Dover to terminate at Ledgewood. The earliest completed sections of an upgraded highway were completed from Livingston Circle to Whippany, with the bridge over the Passaic River completed in 1930. From there the road was extended to the Mount Tabor Road (Route 53), and finished at Ledgewood. In Essex County, the route that the highway would be constructed along was contentious from the start. In 1930 and 1931, three proposals for arteries were presented, all paralleling existing railroads. Though demands to decide a route and begin construction extended to at least 1937, no  highway was ever constructed, and the road terminated at West Orange. To solve this issue, a new route for Route 10 was designated in 1952 to run along a new, never-built alignment farther to the north, running through Belleville, Bloomfield, Glen Ridge, Montclair, West Orange, and along the Livingston/Roseland border, roughly along much of the routing of present-day CR 611 (Eagle Rock Avenue), and following its current alignment through Morris County to Ledgewood. A spur of the route was also planned in 1952 to run from Montclair south to Orange. A year later, in the 1953 New  Jersey state highway renumbering, Route 10 was defined onto its current alignment, with its eastern terminus moved to Prospect Avenue in West Orange. In 1998, the Ledgewood Circle at the western terminus of the route was replaced with a signalized T-intersection. In the mid-2000s, an $11.5 million project was undertaken to improve safety on the portion of Route 10 in Hanover and East Hanover Townships by widening existing lanes and adding turning lanes to the road. Joint Resolution No. 3, page 844, of the 160th Legislature (1936) designated Route 10 as the American Legion Memorial Highway in honor  of the services of the members of the American Legion in World War I.
