Broadway, Toole, & California Intersection Improvements

How can we improve the intersection of Broadway, Toole, and California? The City of Missoula and the Montana Department of Transportation want to hear your thoughts! Your comments, along with several other factors such as costs, safety, traffic operations, right-of-way impacts, and constructability will be used to shape the outcome for the final intersection configuration.

Learn more about the project goals, project phases, and design options below. In the coming weeks we will have an update on the intersection design selection - stay tuned!

PROJECT PHASES: Concepts to Completion

This intersection involves many complex factors that must be carefully considered before a new design can be implemented. The City of Missoula and the Montana Department of Transportation are following a Federal Highway Administration (FHWA)-approved process to guide the selection and implementation of a new intersection design. The phases of this process are outlined below. We are currently at the Intersection Control Evaluation Stage II step in the process and will be selecting a preferred concept in the coming weeks. Stay tuned and check back here for updates as we progress this project towards completion!

INTERSECTION CONTROL EVALUATION: STAGE II

The following intersection options are being evaluated through the Stage II process of the Intersection Control Evaluation study. Several factors, including safety, traffic operations, environmental and community considerations, right-of-way impacts, and constructability and phasing are being considered as we move towards a preferred concept. Each of these factors will be analyzed by our contraced design team, WGM, and published in a final report with a recommended intersection design. The City of Missoula and MDT will review the report and determine a final configuration to be designed and constructed.

OPTION A: ROUNDABOUT

OPTION A: ROUNDABOUT
PROS	CONS
Realigns Toole Avenue and removes the westbound slip lane which then eliminates vehicle weaving while approaching Russel St Intersection. Roundabouts offer safety and operational benefits: Reduce crash severity Reduce the number of conflict points Lower vehicle speeds Simplify driver decision-making Promote continuous traffic flow Shorten pedestrian crossings and provide pedestrian refuge islands Provides complete non-motorized facilities on all four legs of the intersection Removes movement prohibitions at the intersection Balances peak and non-peak hour operations at the time of opening but does not remains balanced over time. Consistent with planning documents and long-term vision for the neighborhood	Westbound and northbound approaches for vehicles become constrained over time, resulting in much longer queing time than other alternatives Reduced capacity on westbound and northbound could limit redevelopment potential in the neighborhood Requires the greatest amount of right-of-way acquisition Potentially greater impacts to adjacent business access Higher construction costs compared to other options

Questions

Share The extra lane shown in the roundabout design- east bound, Broadway onto Toole- is an extreme danger to pedestrians crossing Broadway on the west side of the intersection. This is known as the pedestrian double threat. Drivers and bikers are also in grave danger with the extra lane, as there are blind spots and drivers will be changing lanes in the roundabout. The extra lane causes a 'fastest path' to be way too high for drivers (especially aggressive drivers). Without seeing the intersection evaluation report, we cannot make an informed decision on the alternatives, nor can we advocate to others who rely on our expertise with street design. Was a pure single lane roundabout evaluated? It would be relatively easy to merge the two approaching lanes from Russell/Broadway into a single lane, before the roundabout. If we are serious about Vision Zero, and preventing injuries and deaths on our streets, then a pure single lane roundabout must be evaluated and shown to the public _before_ the public can make an informed decision or opinion on the best way forward.

Bob Giordano asked about 1 month ago

Hi Bob -
The Intersection Control Evaluation step that we are in has two stages. Stage 1 identifies all potential intersection configurations and shortlists only those configuations that are feasible and goal-aligned. Stage 2 involves a detailed evaluation of those shortlisted alternatives and provides a recommendation for a preferred concept. The single lane roundabout was not shortlisted (carried forward) to the Stage 2 analysis because it was predeicted to be at or over capacity on multiple approach legs of the intersection upon opening for use on Day 1.

Bob Giordano asked 29 days ago

Hi Bob,
More or less — the general treatment of the non-motorized facilities (i.e. sidewalks, bike paths, etc.) along Broadway has been identified, but the final design has not yet been completed. The current concept calls for these facilities to be separated from vehicular traffic. Based on design guidelines, it is anticipated that the intersections will include shared use paths, while the midblock segments may transition to a bike lane adjacent to the sidewalk (located behind the curb and still separated from traffic).
Share I prefer the roundabout design rather than traffic signal, however it needs to be a single lane and the entrance angle needs to be increased to reduce speeds, this will reduce accidents and the severity of accidents for both motorists and pedestrians. The city needs to take more proactive measures to reduce vehicle speeds in town to save lives and improve quality of life for those that live here, rather than prioritizing a few minutes of travel time for motorists passing through. on Facebook Share I prefer the roundabout design rather than traffic signal, however it needs to be a single lane and the entrance angle needs to be increased to reduce speeds, this will reduce accidents and the severity of accidents for both motorists and pedestrians.

Bob Giordano asked about 1 month ago

Bob, once completed the Intersection Control Evaluation (ICE) report will be posted to this site. The stage in which public comment is taken is now through 7/23, during the ICE analysis so that we can better understand community input at this intersection. Once the ICE report is finalized, the stakeholders (MDT and City of Missoula) will select an intersection configuration based on the following factors: safety, traffic operations, environmental and community considerations, right-of-way impacts, and constructability/phasing. The reason we cannot leave the survey open after the report is finalized is because the community input will be included in the report.
Our project schedule indicates that we'll wrap up the ICE report and select an intersection at the beginning of August. We need to select that design so we can move forward with design and push to be in construction as early as next summer.
Share Here is some background to our question: It is essential that the signal at Broadway/Toole/California is converted to a modern single lane roundabout. There have been no confirmed injuries at the Missoula roundabouts, while there is an injury about every day at a Missoula traffic signal. A conversion to roundabout at this location is projected to save money, time and lives. It is very important that the roundabout be a pure single lane roundabout with no extra lanes. The two lanes coming from Russell, for instance, will need to merge into one lane well before the roundabout. It is also essential that this roundabout not incorporate 'fast exit design' principals, as that type of design causes crashes and stress, with no benefit in an urban area. Let's prioritize putting an end to traffic crashes and deaths, and harmonizing flow.

Bob_But asked about 2 months ago

Thank you for your question and your concerns about costs.
We are currently in the first phase of the project, known as the Intersection Control Evaluation (ICE). During this step, we’re evaluating multiple factors, including safety, traffic operations, environmental and community considerations, right-of-way (ROW) and property impacts, as well as constructability and phasing.
While the hard costs for construction for each design option will be estimated and considered under constructability and phasing, we’re also looking beyond upfront costs. We're using a comprehensive approach that includes both Life Cycle Cost Analysis (LCCA) and Benefit Cost Analysis (BCA). These methods account for not only design and construction costs, but also long-term operation, maintenance, safety benefits, traffic efficiency, and community impacts.
Stay tuned as we continue through this process.
