render a number of land parcels into
unusable fragments. Such land
gained in excess of real footprint is
not suitable for other uses, such as
park land or an adjacent trail. The
intersections (particularly at Ledge
Street, with its seven-lane approach)
are notably larger than anything now
existing on any surface street within
the City of Nashua.

ing east/west traffic now on Amherst

other locations (most obviously, to
Franklin Street, thereby crossing
Main Street away from Railroad

design speed is incompatible with the
densely developed urban fabric (or
what should be such fabric) in the
road corridor. Design speeds in the
40-50 miles per hour range are
appropriate for suburban arterials, in
which mobility is the highest consid-
eration. For urban streets for which
access and urban street values are the
primary consideration, design speeds
of around half this amount (i.e., 25 to
30 miles-per-hour) are more appro-

priate.

allel alternate route to the Main
Street crossing of the Nashua River,
one of the most problematical traffic
“bottlenecks” in the City.

* The proposed Parkway provides a
large increment of new access to the
Millyard district, enabling travel
between the Millyard and the north
side of the Nashua River without

requiring the use of Main Street.

However the Master Plan team
developed an alternative which better
meets the goals of the City and Down-
town.

To this end, the planning team
reviewed and analyzed the current pro-
posal, interviewed the community devel-
opment staff, public works staff, and the
regional planning commission staff, con-
ducted a field examination, and applied
national experience from other similar
projects to the design of the Broad Street
Parkway.

ommended beginning with those streets

that are the most simple to convert (the

“orphans”) because they are not paired

with another one-way street. Streets were

categorized as follows:

* streets that are less than 30' wide and
are too narrow to convert to two-way
movement with on-street parking

* — streets that can be easily converted
because they are wider than 30’ and
are not paired with a street in the
opposite direction

Streets:
Access and Connectivity

1N GREAT CITIES STREETS are more than a means of simply 7p
moving traffic. Streets are just one of the many components
creating the public realm.

This Master Plan proposes a new framework of streets and
blocks for Downtown Nashua. The framework includes con-
verting one-way streets to two-way streets, improved

streetscaping, and alignments of new streets.
