The Streets Department has released plans for Tower Grove Avenue from Magnolia to Shaw during the Kingshighway construction. From https://www.stlouis-mo.gov/government/departments/street/index.cfm
NOTE REGARDING TOWER GROVE: A road diet and buffered bike lanes on Tower Grove Avenue from Magnolia to Shaw are part of Phase III of Bike St. Louis and all partners are committed to executing that plan. When the Kingshighway bridge construction begins in early 2015, the following things will happen:
1) The East side of Tower Grove Avenue from Magnolia to Shaw will be posted “No Parking” between 7-9 am and the west side will be No Parking between 4-6 pm;towing enforced.
2)We will paint a bikeable shoulder to be used by bicyclists during these peak times. We will maintain the share the road markings in the outside traffic lanes for use by bikes at non-peak times (when parked cars are present).
3) In addition alternate bike routes will be signed as a detour just as we do with vehicle traffic.
4) Alternate routes for cyclists will include creating a biking and walking friendly renovation of the Thurman Underpass.
5) Traffic levels will be monitored and evaluated regularly for changes – This could include additional parking restrictions or reducing parking restrictions and adding bike facilities.
We will install the full Phase III Bike St. Louis improvements along Tower Grove Ave as quickly as possible after monitoring how the closure is affecting all forms of traffic. We look forward to adding this and many more signage and markings to make City of St. Louis streets better for bicycles!
