Sawcut in asphalt creates maintenance problems; especially within a bike lane. In this example, the cut was created when City of Tempe upgraded curbs for ADA purposes (Spring 2018, Warner Road and Dorsey.
Cutting into a road surface creates maintenance problems. Since the city is ultimately responsible for it, there are a set of rules, permits, and fees imposed on whomever might be doing the digging, typically an adjoining property owner (for, for example a new driveway) or utility companies, or the city itself (see example photo at right).
The aftermath of any cutting or digging in a road is particularly problematical for bicyclists when it results in longitudinal gashes/gaps/cracks… and is particularly problematical when the crack is within a Bike Lane because it can reduce the usable width to the point where traveling within the BL becomes impossible to do safely; and furthermore these dangerous conditions are unlikely to be appreciated or even noticed by motorists.

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/Fall 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.
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→
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
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?).

When 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→
For background on the SLM (Shared Lane Markings, a.k.a. sharrows) on the phoenix-side, see here, and more pictures here. That first link has an explanation as to why this bridge is an important and useful link for bicyclists. Continue reading Guadalupe and I-10 Bridge→
Let me start by saying I really like road diets (a.k.a. lane diets), because they have at least the potential to reduce motorist’s peak speeds, while maintaining flow. Continue reading Broadway Road Lane Diet Tempe→
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.
