The road forms a short north-south route on the south side of the Phoenix metropolitan area, from Interstate 10 to State Route 87 on the county line in Chandler, a large suburb of Phoenix. The road is 10 kilometers long and handles 17,000 vehicles daily.

Not to be confused with the Northern State Parkway in New York.
The Northern Parkway is a parkway and freeway in the U.S. state of Arizona, located in the Phoenix region. The highway forms an east-west route through the western suburbs and has a planned length of 20 kilometers.
The Northern Parkway is part of Northern Avenue, an east-west connection from Loop 303 to US 60 in Glendale. Halfway through you cross the Loop 101. Only the western part between Loop 303 and Dysart Road is a freeway, the rest is an urban arterial. The highway has 2×3 lanes.
Northern Parkway is built through Maricopa County and therefore has no road number.
According to allpubliclibraries, in 2003, the first plans arose to upgrade Northern Avenue in Maricopa County to a freeway. The cost was then estimated at $307 million. In 2004, a local VAT increase in Maricopa County was approved to build the highway, but after costs increased further in 2006, it was decided to use the revenue from the VAT increase to run the western part, and the will be financed differently for the rest of the route. The interchange with Loop 303 opened in late 2013, as did the carriageways up to Dysart Road, but the flyovers at Reems Road and Litchfield Road were still missing. These were completed in January 2015.
The remainder of the route will be constructed in phases between 2015 and mid-2024, including the flyovers at Reems Road and Litchfield Road. The first section between Dysart Road and 111th Avenue should be opened by mid-2022.
Phoenix HOV system
The Phoenix HOV system is a network of HOV lanes in the Phoenix, Arizona metropolitan area. HOV lanes are lanes for carpoolers and buses and are normally the leftmost lane. Most freeways in the Phoenix area have HOV lanes, it is one of the larger networks in the United States. In 2013, Phoenix had approximately 525 kilometers of HOV lanes.
HOV lanes come in 5 different shapes;
- separated by a barrier
- separated by a buffer strip
- separated by single mark
- separated alternating lane
- emergency lane
Most HOV lanes in the Phoenix area are separated by single marking or a buffer lane. Detached HOV lanes are rare. In Arizona, solo drivers driving a hybrid car are also allowed to use the HOV lanes. All HOV lanes in the state of Arizona are in Maricopa County, which includes the city of Phoenix. There are also no HOT lanes in Arizona.
The first proposals for HOV lanes in the Phoenix area came from the private sector in the form of HOT lanes. In 1993, a consortium proposed building HOT lanes along Interstate 10. In 1997, HOT lanes were proposed along US 60 in Mesa. In 1997 and 1998, ADOT proposed building HOT lanes along I-10 and I-17, but none of these proposals were implemented.
An extensive network of HOV lanes has been constructed, most of them after 2000. The oldest HOV lanes were probably those of the I-10 near downtown, when this tunnel route was opened in 1990. After that, HOV lanes were built along I-10 to Loop 101 to the west and Loop 202 to the south, as well as I-17 from I-10 north to Loop 101 and US 60 on the westbound stretch through Mesa.
In 2004 an extensive network of HOV lanes was financed with Proposition 400, in the plan 930 kilometers of lanes were constructed and on top of that 480 kilometers of HOV lanes, which more or less comprise the entire urban highway network. The HOV lanes also became more advanced in this plan, with direct HOV connections between highways, for which junctions had to be expanded. Between 2005 and 2012, large-scale HOV lanes were constructed along the entirety of Loop 101 and the western portions of Loop 202, as well as SR-51 and I-17 further north to SR-74, as well as the remaining portion of US 60 through Mesa. .
Until 2025, HOV lanes must also be realized on all remaining highways, these projects are all financed from Proposition 400. After 2020, direct HOV connections between the highways must also be built at important junctions, in 2005 the costs were estimated at more than $ 400 million. A total of $1.1 billion must be invested in the HOV system between 2005 and 2026. When these projects are completed, Phoenix will have one of the most comprehensive HOV systems in the United States. No other urban area has such a large share of the network with HOV lanes as Phoenix.
HOT / Express lanes
The construction of HOT lanes or express lanes is currently being kept open as an option, but has not yet been specifically planned. Phoenix is the largest metropolitan area in the United States where there are no toll roads.
