The Warner Avenue Street Widening project has a longer construction schedule than the protected bike lane project. Construction phasing is paramount for reducing the cost and potential schedule impact for both projects. Two major construction activities that can start as part of the widening project prior to bike lane construction are utility relocations and storm drain main west of railroad. Primary street widening construction work can be ahead of the bike lane project. Temporary traffic control measures and design features such as temporary asphalt concrete (AC) berm can be used for traffic safety and temporary drainage purposes. Another element to be considered is integrating the design with the Warner Avenue widening and Standard Avenue protected bike lane projects. Both projects are expected to be in construction simultaneously. Therefore, providing design solutions for the ultimate condition will reduce the construction cost for all three projects. Based on our experience working on identical projects —as well as our recent working history with the City on the Santa Ana Boulevard and 5th Street Bike Lane, Warner Avenue Improvement, and Main Street Corridor Improvement projects within the same area in the city —we have prepared our approach to the primary design elements of the project. Forms of separation —A successful bike lane facility seeks to provide more protection for bicyclists specifically at vehicular and pedestrian conflict zones. Choosing the right blend of form of separation will enhance safety, while considering construction cost and right-of-way impacts. Per the FHWA Separated Bike Lane Planning and Design Guide, raised median width can be reduced to 16 inches in constraint areas. Delineators can be installed on median noses where visibility for large vehicles is a point of concern. Bus stop treatment — Bus stops are a point of conflict between pedestrians and bicyclists. Providing advance warning signage and striping for the bike lane will reduce chance of a collision at bus stops. Other treatments can be utilizing a raised crosswalk at the transit stop island platform. This option will result in bicyclists reducing their speed as they get close to the bus stop. N ..
