Supplemental Project Study Report
Bellam Boulevard/I-580 Interchange
Alternatives Analysis Study
Prepared for:
San Rafael
Redevelopment Agency
Prepared by:
TAMS Consultants, Inc.
October 1994
Copies of the full report are available for viewing at the Public Works Department
*14 o1 1 N-MMMM Uyi • '
Bellam Boulevard is a heavily -travelled arterial route which provides the primary access to
East San Rafael. It crosses beneath Route 101 and I-580 immediately to the south of the
junction between these freeways, and on- and off -ramps are provided which connect Bellam
Boulevard with freeway traffic in each direction. This results in heavy traffic volumes and
turning movements at closely -spaced signalized intersections between Andersen Drive and
Francisco Boulevard East. A solution is needed in order to relieve the traffic congestion
at this location and increase the capacity of Bellam Boulevard for local traffic.
A primary objective of the study process was to develop alternatives that responded to
community needs and desires. To achieve a clear understanding of the community concerns,
the study team worked closely with a Resource Advisory Committee to develop a statement
of goals and objectives for the project. The goal of the study was agreed as 'To develop and
define the most beneficial and cost effective set of roadway improvement alternatives that will
alleviate traffic congestion in the vicinity of the Bellam Boulevard/I-580 Interchange, and be
consistent with local community goals and objectives" Specific objectives to be met were
defined in the areas of traffic operations, compliance with design standards, environmental
considerations, compatibility with public transit, and cost effectiveness.
The initial stages of the study consisted of defining and comparing as many ideas for
solution of the Bellam Boulevard traffic problem as appeared to be potentially viable. The
ideas were compiled through a process of brainstorming and soliciting suggestions from
representatives of agencies and the community. At this stage of the study, the ideas were
referred to as concepts, to distinguish them from the selected alternatives which were
developed in more detail after the screening out of less desirable concepts. In this study,
the initial number of concepts totalled eighteen, and a nineteenth was added before
selecting the alternatives for further development.
It was found that the concepts could be categorized into one of the following four
circulation categories, according to where access to and from I-580 (and Route 101) occurs.
1. Separate access points not using Bellam Boulevard
2. Full interchange at Bellam Boulevard
3. Full interchange at or near Irene Street
4. One-half interchange remains at Bellam Boulevard
The concepts were rated against each other using a matrix analysis procedure which
evaluated how each concept complied with each of the project objectives. By this method,
concepts that offered few advantages or cost too much were systematically screened out at
an early stage. The results of the screening process were shared with the Resource Advisory
1
Committee (RAC), and after two meetings, a consensus was reached to select four concepts
for more detailed development as alternatives, one representing each of the categories
identified above. Before evaluation, the alternatives were subjected to a value engineering
(VE) study, as a result of which one alternative was dropped from further consideration, and
modifications were made to features of the remaining three alternatives. The selected
alternatives are briefly described as follows, with an estimate of the project cost, inclusive
of right-of-way and other overhead costs:
Alternative A: ($23.0 million) Alternative A is a type of split interchange that has access
points located on two separate streets. It became one of the four alternatives because it is
relatively inexpensive, it is based upon the original 1985 PSR concepts, and it is effective
in reducing the congestion on Bellam Boulevard. A new overcrossing of I-580 would be
located about 300 feet south of Irene Street, connecting Kerner Boulevard to Andersen
Drive. Ramps to and from westbound I-580 would connect with Kerner Boulevard roughly
700 feet south of Bellam Boulevard; eastbound ramps would connect with the new
overcrossing south of Irene. Three of the four freeway connections and two signals would
be removed from Bellam Boulevard.
Alternative B: ($27.0 million) Alternative B attempts to modify the existing interchange
at Bellam Boulevard, rather than relocate the problem elsewhere. Since a major problem
of the existing conditions is the fact that there are three signals in a distance of 400 feet, a
key improvement is elimination of the middle signal. This is accomplished by routing the
west/northbound ramps below the I-580 roadways to form a single point intersection with
the eastbound ramps. A new Andersen -Kerner connector/I-580 overcrossing would be
provided at or near Irene Street. The VE team recommended that this alternative be
dropped, due to its high cost and the limited relief of traffic congestion which it offers.
Alternative C: ($24.1 million) This alternative would provide an "urban diamond'
interchange located about 300 feet southeast of Irene Street. The intersection of the ramps
is centered over I-580 to minime impacts to the properties fronting along Francisco
Boulevard and to avoid the space limitations imposed by the PG&E towers east of Francisco
Boulevard. It requires relatively little right-of-way acquisition and relocates all freeway
connections to a new, single, and identifiable location. This alternative offers the greatest
opportunity to separate local from freeway traffic. Traffic congestion on Bellam Boulevard
is reduced by removing the freeway connections and two signals.
Alternative D: ($20.9 million) Alternative D would convert the existing diamond at Bellam
into a one and one-quarter diamond. Movements to and from Route 101 would remain in
their familiar location. Movements to and from the east (I-580), and from EB I-580, would
be relocated at a new overcrossing of I-580, 300 feet south of Irene Street. Several options
were considered for the arrangement of the ramps at Bellam Boulevard, preferably
2
eliminating one of the traffic signals along Bellam Boulevard. These included (1) a five -leg
intersection at Francisco Boulevard East, (2) braiding of the NB on-ramp with the SB
lane(s) of Francisco, or (3) rerouting SB Francisco Boulevard traffic north of Bellam
Boulevard, so as to allow use of Francisco Boulevard by NB traffic to Route 101. Of these
options, the five -leg intersection was chosen for incorporation in Alternative D.
The alternatives were evaluated using a matrix process, in consultation with the RAC. The
results of the evaluation process, which received the concurrence of the RAC, were that
Alternative C best met the goal and objectives of the study. Features favoring this
conclusion included:
■ Its ability to reduce traffic congestion on Bellam Boulevard
■ Minimal disruption to traffic during construction
■ Improved and simplified access to regional transportation system
■ Conceptually simple nature of the "urban diamond"
■ Separation of freeway traffic from local traffic
A potential drawback lies in the fact that Alternative C, as well as Alternative D, does not
easily break down into low cost construction stages that yield early results.
The conclusion of the study is that the City should proceed with the preparation of a
preliminary design and environmental analysis for the preferred alternative, with a view to
expeditious completion of construction, and relief of the current traffic conditions
experienced along Bellam Boulevard.
