safe accommodation of bicyclists can be provided at reasonable cost as part of such replacement or rehabilitation , then such bridge shall be so replaced or rehabilitated as to provide such safe accommodations .” ( 23 U . S . C . Section 217 )
Bridge replacement projects on controlled access freeways where pedestrians and bicyclists are prohibited by law should not include facilities to accommodate bicyclists and pedestrians . In cases , however , where a bridge replacement project on a controlled access freeway impacts a non-controlled access roadway ( i . e ., a new overpass over an arterial roadway ), the project should include the necessary access for pedestrians and bicyclists on the non-limited access roadway ( i . e ., paved shoulders , sidewalks , and pedestrian / bicycle crossing improvements ). Existing and planned greenway crossings , both at-grade and below new bridges , should be similarly accommodated during bridge replacement projects .
Retrofit Roadways with New Bicycle Facilities There may be critical locations in the Bicycle Network that have bicycle safety issues or are essential links to destinations . In these locations , it may be justifiable to add new bicycle facilities before a roadway is scheduled to be repaved or reconstructed .
In some places , it may be relatively easy to add extra pavement for shoulders , but others may require removing trees , moving landscaping or fences , or regrading ditches or hills . Retrofitting roadways with sidepaths creates similar challenges . Improvements in these locations are typically recommended in the long-term .
Some roads may require a “ travel lane conversion ” ( TLC ) solution in order to accommodate bicycle facilities . TLCs involve removing vehicle travel lanes and replacing these lanes with on-road bicycle facilities and sidewalks or sidepaths . Further study may be necessary for recommended TLCs to ensure that capacity and level-of-service needs are balanced against bicycle level of service needs .
Signage and Wayfinding Projects Signage along specific routes or in an entire community can be updated to make it easier for people to find destinations . Bicycle route signs are one example of these wayfinding signs , and they should be installed along routes independent of other signage projects or as a part of a more comprehensive wayfinding improvement project .
