Beginning in 2016, working from west to east, the entire length of Warner Road in City of Tempe has been resurfaced. The last segment, was just completed in May 2022.SMOOTH!
Warner Road in City of Tempe extends the entire width of the city here; bounded by I-10 on the west, and SR-101 / Price Road on the east; a bit over 5 miles. It is very straight, “5 lane” (2 thru lanes; center/left lane), plus bike lanes arterial road posted speed limit of 45.
I’m not sure how long the bike lane has been striped; probably before I arrived here in the early 1990s; here’s the modern history
2016 Warner fully resurfaced from I-10 to Kyrene this project was BADLY needed, in particular the intersection at Kyrene was sub-standard and dangerous for bicyclists.
2018 Warner fully resurfaced from east of Kyrene to Rural
2020 Added marking for “combined turn lane” where the BL drops
2022 Warner fully resurfaced from Rural to SR101/Price.
Although there are some irregularities around the freeways, and around ASU research park (more on that later), the nominal plan for the road is as above in the street mix diagram, and as pictured at right. The “old” (top Streetmix, above) plan had minimum-width bike lanes (4 feet of usable width; plus gutter). The “new” (bottom Streetmix, above) plan simply swapped 1 foot out of the right lane, and added it to the bike lane making the usable width a more-comfortable 5 feet. The thermoplastic green patches, as in the picture on Warner west of Rural, will be added to the new section once the asphalt cures, currently has temporary striping.
It’s unlikely this would have much/any impact on safety for cyclists, but it is definitely more “comfortable”. [It should be noted that a combined width of 16 feet is just barely marginal for side-by-side sharing between a nominal bicycle and a large vehicle like Bus / truck — this is a warning to those who want to shoehorn bike lanes everywhere and anywhere, even when there’s not enough space]
A quick review of the most recent 13 years of crash data (2009 – 2021) show 39 reported bike-MV crashes along Warner; 5 of them serious (none fatal):
- Motorist bad left into driveway
- Bicyclist ride out from driveway, attempting to cross Warner
- counter-flow sidewalk cyclist in crosswalk
- Motorist faulted “other”; angle
- Bike sidewalk counter flow struck by motorist leaving a driveway
I didn’t look individually at all the other 34 incidents; most involve sidewalk / crosswalk / driveway issues. Leave a comment if you’re interested and i can pull details.
For comparison, there were 2044 crashes of all types.
