The 12th Ave/Speer Blvd/Elati St Central Denver Signal Project aims to improve multimodal safety and provide green infrastructure improvements at this complex intersection and access point to the Cherry Creek Trail.

The project will install a new traffic signal at the intersection to enhance the crossing experience for all users and upgrade adjacent damaged curb ramps, sidewalks, and curb and gutter. The project will also consider reconfiguring the triangle formed by Speer Boulevard, 12th Avenue, and Elati Street with the goals of shortening pedestrian/bike crossing distances, creating better motorist sight lines for vehicles turning on/off Speer, and expanding the existing green space to include green infrastructure for stormwater treatment. Furthermore, the green infrastructure improvements will aim to create a neighborhood amenity matching the adjacent land use.

All improvements will be designed and constructed to current City and County of Denver (CCD) standards and specifications, meet Pedestrian Right of Way Guidelines (PROWAG) and achieve ADA compliance, while following the Mile High Flood District's Volume 3 Criteria Manual and DOTI's Ultra-Urban Green Infrastructure Guidelines.

Frequently Asked Questions

What are the goals of this project?

• Maintain safety and access for drivers
• Enhance safety and comfort for pedestrians and bicyclists
• Support transit service throughout the corridor
• Support business access and activity
• Support neighborhood context, network roles, and corridor "permeability"
• Implement a fiscally responsible solution that can be advanced in the near term

Why Alameda? How did we get here?

Alameda is part of Denver's High Injury Network (HIN). The HIN is a collection of 5% of Denver's streets that account for 50% of serious and fatal collisions in the City. The HIN has disproportionately high rates of traffic crashes resulting in death or serious bodily injury.

In addition to being on the HIN, Alameda is a priority for DOTI because of 311 community concerns. When the corridor was analyzed, preventable crashes (rear ends and turning vehicles) were higher in this section than DOTI would like to see. Upon further analysis, these crashes were a result of speeding and lack of left turn lanes.

In 2018, DOTI evaluated and implemented the Corona Street turn restrictions and, in 2020, completed "after" data collection and safety analysis on Alameda Avenue to determine appropriate next steps. This initiated a corridor-wide study along W Alameda between Franklin and Lincoln, to determine the impact of a lane reduction and how to best repurpose that lane space to enhance the safety for all users. These findings were presented to the community in May 2020.

From 2020-2023, DOTI conducted an alternatives analysis of different concept designs to explore safety improvements along Alameda from Logan to Franklin.

Will this project cause an increase in congestion on side streets, like E Virginia Ave and E Bayaud Ave?

Based on DOTI's analysis, the impact to side streets will be minimal; no more than 10% of vehicles will reroute throughout the entire day. A diversion analysis anticipates that Virginia Avenue will experience approximately 490 additional vehicles per day.

There are minimal pedestrian/bicycle crashes along this section of Alameda, so why is DOTI doing pedestrian improvements?

DOTI helps plan and build multimodal improvements to our roadways and neighborhoods to ensure that all modes of transportation are safe for all residents and visitors.

Although no pedestrian and bike facilities are present on Alameda, the improvements will improve safety where pedestrian and bicycle facilities intersect with the corridor. This will make it easier and safer for all users to reach destinations along Alameda regardless of mode choice. The communities along Alameda have long been advocating for safer crossings, this advocacy was advanced by the school crossing guards and families who have noted existing danger along the corridor.

While Alameda may not have a history of many pedestrian and cycling crashes, DOTI heard consistently from residents and businesses along the corridor voicing frustrations over attempting to cross. Specifically, DOTI heard from schools, crossing guards and families who either have attempted to cross Alameda or avoid crossing because of existing danger.

What is the budget of this project?

$330,000 was approved for the design and construction of safety improvements. Part of the funding was approved by voters through the RISE Bond. Additional funding was secured through Vision Zero, allowing a speed reduction to be implemented throughout the corridor.

Why a Lane Reduction?

According to the U.S. Department of Transportation, reducing the number of lanes on a multi-lane roadway can reduce crossing distances for pedestrians and slow vehicle speeds. Reducing from a four to two lanes and including center left turn lanes is shown to reduce crashes 19-47%.

How does this project consider future increases in density?

A long-term analysis was conducted. Projects are done with the assumption that Denver will continue to grow. The lane reduction project considers future growth of Denver. The recommended facilities will not only help improve safety today but advance safety into the future as traffic increases along Alameda.

Is this project working with Denver Council of Regional Government's (DRCOG) transit goals for the entire Alameda corridor?

While DRCOG is currently doing an Alameda Corridor Plan, this is a long-term plan that will not be implemented in the foreseeable future. While both project teams are working tangentially, DRCOG's plan will not affect plans for the lane reduction.

DOTI's plan is a short-term project and does not currently have any modifications for transit.

The intersection with the most issues is Downing and Alameda. Why can't DOTI make changes here?

When DOTI did its analysis, it was determined that if more left turns were allowed throughout the corridor, a left turn at Downing would not be needed. This is good news, since the current signal at Downing would need to be replaced, adding expense to the project's budget!

Am I having déjà vu? Wasn't a lane reduction attempted on Alameda several years ago?

DOTI installed a lane reduction on Alameda back in 2008-2010 timeframe. In the eastbound direction, there was a lane drop at Downing necessitating a lane merge before Downing which resulted in stacking of vehicles on the eastbound approach to Downing Street with one lane fully queued and the other lane free flowing. During this time the Alameda average daily traffic was over 20,000. It is now much lower, so Alameda is a better candidate for a lane reduction.

The City and County of Denver is working to establish a future vision for the Alameda Underpass near the Baker, Valverde and Athmar Park neighborhoods and the Alameda transit station.

We have conducted a comprehensive study of the Alameda Underpass between Santa Fe Drive and Cherokee Street to establish a multi-modal vision for the Alameda Underpass area and help plan for the implementation of improvements and design of the underpass. The project identifies benefits and challenges of various ways the City might address the corridor’s identified needs, and vets those options with very preliminary conceptual design.

The project’s final Conceptual Study Report was released in May 2019. It identified a preferred roadway cross-section alternative and helped plan for the future, potentially phased implementation of these improvements.

The Quebec Street Bridge over Airlawn Road, just south of I-70, was built in 1961 and rehabilitated in 2012. This bridge has been deemed one of the poorest quality bridges in the City, posing safety concerns with inadequate sight distance for drivers at nearby intersections.

In 2017, Denver voters approved Elevate Bond funding to ensure the safety of this infrastructure is one day brought up to standard. In early 2022, work began on an improved design for this section of Quebec Street to address these safety concerns.

Read more about Quebec Street Bridge over Airlawn Road

The Quebec Street Pedestrian and Mobility Improvements Project will enhance neighborhood safety, comfort and access along Quebec St and 17th Ave.  Missing sidewalks in the area make it difficult, uncomfortable and, at times, unsafe to walk or roll through the neighborhood or wait for a bus.  Likewise, Quebec St is one of 27 streets that make up Denver’s High Injury Network, within which 50% of all fatal crashes and serious traffic injuries occur.

To improve pedestrian safety and mobility, the project will fill 2.1 miles of sidewalk gaps along Quebec St (between 12th Ave and Montview Boulevard) and E. 17th Ave (from N. Monaco Parkway to Rosemary St), add ADA compliant ramps at all intersections within the project scope, and make limited upgrades to five transit stops along Quebec St.  The city will also upgrade the traffic signal at Quebec St and E. 17th Ave to enhance safety for pedestrians and improve traffic operations.

Olsson was retained by Mile High Flood District (MHFD) and the City and County of Denver to provide design of storm drain system improvements in the Marston Lake North Drainageway. The main objectives of the project are to separate stormwater flows from the Bowles Lateral, improve drainage and alleviate high ground water near the properties adjacent to the Bowles Lateral at Saratoga Place, and improve the overall drainage and reduce street flow through the project area.

The general design concept is to install new storm drain infrastructure to collect and convey 100-year flows from West Wagon Trail and South Field Way to the existing storm drain system downstream of the Glenbrook Pond. Storm flows will be separated from the Bowles Lateral with the improvements. The project will be completed in two phases.

Phase I construction began in December 2022 and was completed on June 30, 2023. 

Phase I consisted of improvements from the Glenbrook Pond outfall to just upstream of the Bowles Lateral. Storm drain lines, inlets, and manholes were installed in West Garrison Street and South Garland Street, then across the Bowles Lateral to West Saratoga Place. As part of the project Bowles Lateral was put into a 60-inch pipe. A headwall and wingwalls were constructed at the culvert entrance. An 8-inch French drain was installed along the new Bowles Lateral pipe in the vicinity of the ditch to collect groundwater. Curb Ramps were replaced at the intersections of South Garrison Street and South Holland Way, South Garland Street and West Garrison Street, and West Saratoga Place and where Wagon Creek Trail crosses West Saratoga Place. On West Garland Street, curb, gutter, and sidewalk were be replaced.

Construction for Phase II began in Spring 2025, and will last approximately 5 months.

Phase II includes installing improvements upstream of the Bowles Lateral, and at Hoyt Street and West Saratoga Place. Phase II includes installing 36- and 42-inch storm drain trunk line with laterals and inlets along West Saratoga Place, West Wagon Trail Drive, and South Field Way. The existing storm drain system in South Field Way will be connected to the new system at the intersection of South Field Way and West Wagon Trail Drive. Construction will also include curb ramps, curb, gutter, and sidewalk replacement. Additionally, inlets, laterals, and storm drain trunk line will be installed, conveying storm flows to the existing system in Hoyt Street, ultimately conveying flows to the Glenbrook Pond.

Project Overview

The Mar Lee residential neighborhood was constructed primarily in the mid to late 1950s. Consistent with development at that time, there are no underground stormwater pipes in this project area. Therefore, stormwater runoff is currently served only with curbs, gutters and roadway cross-pans. Multiple stormwater studies have indicated the potential for excessive stormwater in the streets as well as flooding during heavy storms.  

The new storm drain system will improve greater protection from flooding with as little disruption to the community as possible. Design of the system was completed in 2022 and put on hold due to funding constraints. Funding for construction is now available, and construction is anticipated to begin during the winter of 2025/2026.   

Work will include new storm drains, inlets, and manholes along W. Oregon Place, S. Xavier Street, W. Mexico Avenue, and S. Wolcott Court and will connect into Sanderson Gulch with an outfall just south of Vrain Street. Work will also include utility adjustments, roadway reconstruction, and the reconstruction of some sidewalks, curb and gutter, and curb ramps.
