Northern Parkway
Project
Description
The Northern Parkway is a planned major highway project that
extends 12.5 miles from SR 303/Estrella Freeway (Loop 303) to US
60 (Grand Avenue) and will replace Northern Avenue for a portion
of this distance. The proposed Northern Parkway will be an
enhanced arterial street with grade-separated intersections at
major cross streets to eliminate the major traffic signals on
Northern Parkway. The resulting roadway would have twice
the traffic carrying capacity of a typical arterial and would
enable traffic to flow at average speeds of 45 miles per hour
(mph) as compared to typical arterials with average speeds
between 25mph and 35mph.

NORTHERN PARKWAY ALTERNATIVES
Four Northern
Parkway alternatives have been identified for the corridor from Loop
303 to
Grand Avenue (US
60). The alternatives are:
-
Alternative I -
Northern Avenue Alignment, Option I (with two traffic signals)
-
Alternative 2 -
Northern Avenue Alignment Option 2 (no traffic signals)
-
Alternative 3 -
Southern Alignment, and the No Build Alternative
-
The No Build Alternative
Each of these
alternatives are described in the Draft Design Concept Report (DCR)
at the bottom of this page.
Proposed Action
Based on the
evaluation of the purpose and need (Table 4-1 in the DCR), the
evaluation of other
factors listed in
Table 4-2, and input from agency partners, stakeholders, and the
public, the Northern
Parkway Management
Committee has selected Alternative 1 - Northern Avenue Alignment
Option 1
(two traffic
signals) as described in Sections 4 and 5 of the DCR and as shown in
the concept plans
contained in
Volume 2 of this report. Alternative 1 is the Proposed Action and
some important features
are summarized
below:
Alignment
The preferred
alignment is along Northern Avenue from Grand Avenue to Dysart Road.
Between Dysart
Road and
Litchfield Road the alignment transitions northward to the Butler
Drive alignment. From
Litchfield Road to
Loop 303 the Parkway would follow the Butler alignment.
Design Concept
A wide variety of
design concepts have been investigated. Major issues evaluated
include the level of
access control and
the number of signals.
This alternative
includes only two traffic signals; one at 111th Avenue and one at
107th Avenue; these intersections would provide the only
two median breaks. Intersections of major arterials and the
Northern Parkway
would be grade separated. Committed levels of access control are as
follows:
-
Full access
control between Sarival Road and 115th Avenue
-
Partial access control between 115th Avenue
and 103rd Avenue as well as between 91st Avenue
and Grand
Avenue
-
Between 103rd
and 91st Avenue, the Parkway would be located on a fully access
controlled
bypass
-
Several
alternative access roads would be provided to minimize impacts of
access control
The
ADOT/MCDOT Design
Concept Report for Loop 303 defines the design concept for the
connection between
Loop 303 and the Northern Parkway.
After Alternative
1 is completed, studies will be undertaken to address any additional
improvements that may be needed to meet the needs of neighborhoods
and the motoring public.
Phasing
The Northern
Parkway Corridor is located in a rapidly developing area. It is
recognized that under
current funding
commitments completion of Alternative I is more that 20 years off
and beyond the
current Maricopa
Association of Governments (MAG) Regional Transportation Program
(RTP) and funding program. In order to ensure effective use of
limited resources, it is important that the
Parkway be
constructed in meaningful contiguous segments and that right-of-way
be protected to
ensure completion
of the ultimate facility.
The recommended
phasing is Option 2A - West to East Not Accelerated alternative
described in
Appendix C of this
report. This alternative includes acceleration of the local match
funding from
the City of
Glendale and MCDOT. Elements of this phasing concept from early to
final construction
include:
-
Interim Parkway
construction from Sarival Road to Dysart Road (four lanes) -
at-grade signalized intersections for intersecting
arterials (future locations of GSI)
-
Interim
throwaway widening from Dysart Road to 112th Avenue (four lanes) -
minimal access
-
control
-
Ultimate GSI
construction at Sarival Road, Reems Road and Litchfield Road -
full access control
-
Interim Parkway
and ultimate GSI construction from Dysart Road to the Agua Fria
River including GSI at Dysart Road and EI Mirage Road and the
interim half Agua Fria River Bridge (four lanes) - full access
control
-
Interim Parkway
from the Agua Fria River to 111th Avenue (four lanes plus
auxiliary lanes) - partial access control
-
Ultimate Parkway
from 111th Avenue to 103rd Avenue (six lanes plus auxiliary lanes)
partial access control
-
Ultimate
Northern Avenue street improvements from 103rd Avenue to Loop 101
(six lanes)
-
Interim
throwaway widening from Loop 101 to 91st Avenue (six lanes)
-
Interim
throwaway intersection improvements at 91st, 83rd, 75th, and Grand
Avenues
-
Other funding
sources need to be identified to complete the Parkway concept
based on current projected funding. The above listed
improvements can be completed within the 20 year funding program.
Project
Status
An Inter-governmental Agreement (IGA) was
approved by the City of Peoria Mayor and Council at the August
26, 2008 Council Meeting. The IGA has been approved by the
City of El Mirage and the City of Glendale.
