PROJECT OVERVIEW

Four segments of roadway were re-striped and re-signed in the City of St. Paul to create safer conditions for cyclists on Arlington Ave.: Wheelock Pkwy. to Rice St. and Jackson St. to the Gateway Bike Trail east of I-35E, East Como Blvd.: Wheelock Pkwy. to Nagasaki Rd., Marshall Ave.: Western Ave. to John Ireland Blvd., and Summit Ave.: Mississippi River Blvd. to Lexington Pkwy. Signs related to the bikeways were added and adjusted along the project corridors so that they met current MnMUTCD design standards.

The Arlington Ave. roadway width was reallocated to accommodate new bike lanes; bikeway signing and striping transformed this corridor that previously had no bike lanes. As part of the design, the roadway sections had to seamlessly tie into existing bike lanes at the four ends and existing on-street parking needed accommodating.

The East Como Blvd. segment, although short, required significant work as it transitions through five different typical sections. Isthmus developed several layout concepts for the City to review and select a preferred alternative. A five-legged intersection required design care to assure safety, and clear vehicular and cyclist directions. Specialized right-turn lane signs were designed at Wheelock Pkwy. and Maryland Ave. directing right-turn movements to specific lanes. All new striping was added to accommodate bike lanes within the existing cross section.

Marshall Ave. was unusual in that it was a one-way vehicular roadway with no bike lanes for which the City requested the design of contraflow bike lanes allowing two-way bike traffic while limiting vehicular traffic to only westbound travel. The addition of contraflow bike lanes meant the road could no longer be considered one-way. The one-way signs were removed from the corridor and NO LEFT TURN and EXCEPT FOR BICYCLES signs were added to make the route MnMUTCD compliant, providing proper direction to cyclists and motorists.

At two miles long, Summit Ave., a primarily two-lane divided roadway, was the longest segment of this project. Bike lanes were re-established in each direction with a buffer between vehicular and bicycle traffic to improve cyclist safety for a total of four miles of bike lanes. Additional pavement markings were added to the roadway to increase safety where it transitioned from divided to undivided, providing both cyclists and drivers better guidance. Green bike lane markings were implemented across Lexington Ave. to call attention to the desired bike lane as the roadway alignment shifts at this intersection.
