Mill Avenue — Broadway to Southern — resurface

Thanks to the City of Tempe Streets Dept for contacting me/us about this project. A one mile section of Mill Avenue, from Broadway Road to Southern Avenue, is set to be resurfaced (they call this a “Pavement Preservation”) soon, I think Summer 2017.

existing edge line in the project area along Mill Avenue

This section has edge lines enclosing a small shoulder. (“fake bike lane”). Edge lines generally should not be used on urban arterial roads in this configuration; and especially when they look like bike lanes, and thus are easily confused with bike lanes. The picture of the grate, in the shoulder should be self-explanatory.

Here’s what the City said: Continue reading Mill Avenue — Broadway to Southern — resurface

Warner Resurfacing

Warner Road; typical cross section ~ 68 feet curb-to-curb (google maps sat view before 2016 resurface)

Warner Road is a major east-west arterial that runs through much of the East Valley. It’s continuous from Phoenix (Ahwatukee area, where it forms a loop with Elliot Road, another major e-w arterial), thru Tempe, Mesa, Gilbert. In the city of Tempe it runs the entire width of the city, from wherever exactly it is that Tempe begins (just east of I-10 bridge) to just west of SR101 (google maps)

Warner in this area generally has two through lanes and a designated bike lane (BL) in each direction as well as a continuous center lane, some major intersections have right-turn-only lanes (RTOL), but others do not (more on that later). There are no BLs in the area immediately east of I-10, and there are numerous “dropped” BLs; where the BL is intentionally discontinued to make room for a RTOL. Continue reading Warner Resurfacing

Usable Width and Bike Lanes

These Bike Lanes meet both the minimum overall width and recommended usable width

[Jump directly to Guadalupe resurfacing]

The dimension below all refer to urban streets with curbs and no parking…  Most recommendations for Bike Lane dimensions refer to the AASHTO Guide for the Development of Bicycle Facilities , the general rule is

the minimum bike lane width is 5 ft (1.5 m), measured from the face of a curb or vertical surface to the center of the bike lane line

However, that changes when a gutter pan is involved, more width is required to meet their recommendations —

Along sections of roadway with curb and gutter, a usable width of 4 ft (1.2 m) measured from the longitudinal joint to the center of the bike lane line is recommended

City of Tempe tests ‘Bike Box’

The City of Tempe installed a bike box on the east side of 10th Street at Mill Ave.  Note that in that google street view, there is already a bike box on the west side of the same intersection, installed by ASU according to the news item (apparently ASU and not the City of Tempe has jurisdiction over that piece of 10th street?).

Chandler Boulevard Extension

ChandlerBlvdExt2When the final portion of the Loop 202 / South Mountain Freeway (SMF), the part that connects I-10 to Laveen, gets constructed it will replace Pecos Road. Pecos Road in Ahwatukee will be no more. This would otherwise leave everything west of 19th Avenue inaccessible from the rest of Ahwautkee, except for the freeway. The construction of SMF is supposed to begin summer 2016 and opens late 2019. Continue reading Chandler Boulevard Extension

Funding proposal would add BLs on Chandler Blvd over I-10

Capture2
Chandler Blvd is vastly wide, and lacks bike lanes west of ~ 54th St.

This is pretty interesting for those of us in the Ahwatukee / Chandler area…

City of Chandler has made a request for TA/CMAQ (see also  alameda-drive-tempe-bicycle-pedestrian-proposal for more about TA/CMAQ) funding to add BLs on Chandler blvd between where they stop now (~ 54th St) and continue them to the “far” side of the bridge (City of Phoenix jurisdiction). It’s about .4 miles and the bottom line cost estimate is ~ 600,000 (details are in the link below). The main money driver here is some of the area needs to have curb/gutter/sidewalk relocated in order to make room. See the area on Google Maps.

Alameda Drive Tempe Bicycle / Pedestrian Proposal

Alameda / Tempe funding proposal http://www.azmag.gov/Documents-Ext/ModalApps_2018/BP/TMP-19-BPB-001_Complete-Application.pdf
Door Zone Bike Lanes figure prominently in the Alameda Drive / Tempe funding proposal

If you’ve never read one of these funding proposals before, they’re pretty interesting. This is one of some number of TA / CMAQ Application for FY 2018, 2019, and 2020 Projects submitted to MAG. Phew, lots of initials: TA / CMAQ Transportation Alternatives / Congestion Mitigation Air Quality. MAG is the Maricopa Association of Governments, who has some sort of process to score these things and recommend (decide?) who gets what. They also have relatively detailed cost estimates, e.g. this project’s bottom line is just shy of $2M total; the kicker is the cost split Continue reading Alameda Drive Tempe Bicycle / Pedestrian Proposal
