10' Turn Lane
Existing Conditions - Typical street section
Preferred Option - Remove center turn lane, add bike lanes
View at mid-block
View at intersection(bulb-outs optional)
Option reviewed/rejected - Remove parking one side for bike lanes
Option reviewed/rejected - Widen road/reduce sidewalk
Existing Conditions - Plan diagram (representative segment)
Option reviewed/rejected - Plan diagram (representative segment)

Option reviewed/rejected - Plan diagram (representative segment)
Option 1 - Plan diagram (representative segment)
Pros:• No changes needed to existing curbs or striping• Accommodates vehicle left turns along each block
Cons:• No dedicated bicycle facilities• On-street parking causes potential “dooring” confl ict for
bicyclists on both sides of National Avenue
Pros:• No changes needed to existing curbs• Class II bike lanes are safer than existing conditions or Class
III bike routes• Buff er between bike lanes and on-street parking reduces
potential “dooring” confl icts• Opportunity for pedestrian-friendly intersection bulb-outs• Potential for reduction in travel speeds
Cons:• Removes left turn opportunities for vehicles mid-block• Removes on-street parking near intersections (approx. 74
parallel parking spaces along entire corridor, about 17%)• Added cost to install optional intersection bulb-outs
Pros:• Class II bike lanes are safer than existing conditions or Class
III bike routes• Retains on-street parking (both sides of street) and center
left turn lane
Cons:• Expensive and likely infeasible to expand street and reduce
parkway/sidewalk along one side of the entire corridor (approx. 1.8 miles)
• On-street parking causes potential “dooring” confl ict with bicyclists on both sides of National Avenue
• Narrower travel lanes
Pros:• No changes needed to existing curbs• Class II bike lanes are safer than existing conditions or Class
III bike routes• Retains left turn opportunities for vehicles mid-block• Intersection bulb-outs are possible with this option
Cons:• Removes about 48% of on-street parking along the entire
corridor (approx. 210 parallel spaces total) - see inset diagram showing proposed parking confi guration
• “Dooring” of bicyclists still a possibility next to parking• Added cost to install optional intersection bulb-outs
