Tower Grove Project
The Tower Grove Project on I-64 in downtown St. Louis was completed in late August with the
opening of the ramp from westbound I-64 to Boyle Avenue. The $17.9 million project, which started
in early 2013, was designed to improve traffic flow in and around Kingshighway Boulevard to BJC
hospital. The project:
Replaced bridges at Taylor, Newstead, Tower Grove and Boyle Avenues
Constructed a new interchange at Tower Grove/Boyle
Added two new ramps at Tower Grove and Boyle to support the existing ramps
Built a new roundabout south of I-64 on Tower Grove Avenue
Installed signals at the westbound entrance and exit ramps at Boyle, and at the intersection of
Boyle and Papin
Realigned and installed signals on Clayton Avenue at Tower Grove and Boyle to coordinate
interchange traffic
Built new I-64 pavement between Kingshighway and Newstead and resurfaced I-64 between
Newstead and Sarah
Washington University Medical Center and BJC Healthcare partnered with the department on
funding the project.

Arterial Management

New Arterial Travel Time Index
Arterial mobility is measured by a travel time index, or TTI. These arterial travel times are in a similar format to freeways. Data from MO Route 141 and US Route 67 are presented for both the AM/PM peak for North and Southbound directions. An explanation of how this effort is being completed is included in the following paragraphs. Arterial TTI for a segment of roadway over a peak period is calculated by dividing the average travel time by the expected travel time. The expected travel time is simply the length of the segment divided by the posted speed limit. Due to signalization of arterials, determining a true free flow speed is not practical. For this reason, the posted speed limit is used rather than the free flow speed. A value greater than 1.0 means the average travel time during the peak period is longer than the expected. Because arterial travel times are measured over a segment rather than at a point, the TTI charts display one index value for the entire segment. This means the TTI will be displayed as a straight line between measurement points rather than as a slope from one line to the next as shown on the freeway charts. The travel time indices being presented are the current month and the previous month. A comparison of the previous year will be added as soon as the information is available for analysis. Arterial mobility on MO Route 141 was introduced first, with US Route 67 the second of several instrumented arterial routes to be added in the future. Eventually, as more routes are added to the report, the arterial travel time index will be displayed on a color coded map similar to the freeway mobility map.

8/6/2014 (Wednesday) PM Peak
Location: MO 21 @ Mattis Road (south of I-270)
Event: Intersection crash at Mattis Road caused the Southbound I-270 off-ramp to back up
Time: 5:30 pm 5:45 pm Total Time: 0 hours 15 minutes
Action: At 5:30 pm the PM Peak timing plan 3/1/1 was adjusted to give 19 additional seconds (100 second CL) to the Southbound off-ramp by taking time away from mainline Route 21.
Result: The additional timing allowed the Southbound off-ramp queue to quickly clear. At 5:45 pm the timing change was reversed.

Work Zones Whenever additional travel time is reported, this additional time shall be evaluated using this chart and adequate mitigation measures should begin within the parameters of this chart. TMC and field personnel are partners in the mitigation of traffic and notification of additional travel times should trigger the appropriate response from both parties. Chart is designed to be an additional travel time reference to establish parameters for gauging the travel impact through work zones and to provide guidance for taking mitigation actions. Travel times can be collected or reported via Blue Toad technology, field personnel, call reports, ITS, TMC cameras, etc. Major and Moderate impacts trigger an IAR (Immediate Action Required) event. IAR means work zone user and TMC partner together to take immediate actions to reduce or eliminate distress. During an IAR event mitigation procedures can range from increased driver notification up to and including removal of work zone. Additional mitigation procedures may require involvement of administration through use of the work zone resolution ladder. IAR event can be upgraded or downgraded as conditions change.

Incident Levels
Major Impact Traffic Incident – Road closure > 2 hours Major traffic incidents are typically traffic incidents involving hazardous materials, fatal traffic crashes involving numerous vehicles, and other natural or man-made disasters. These traffic incidents typically involve closing all or part of a roadway facility for a period exceeding 2 hours. Moderate Impact Traffic Incident – Blocked travel lanes/closure 30 min – 2 hours Moderate traffic impact incidents typically affect travel lanes for a time period of 30 minutes to 2 hours, and usually require traffic control on the scene to divert road users past the blockage. Full roadway closures might be needed for short periods during traffic incident clearance to allow traffic incident responders to accomplish their tasks. Minor Impact Traffic Incident – Lane closures < 30 minutes Minor traffic incidents are typically disabled vehicles and minor crashes that result in lane closures of less than 30 minutes. On-scene responders are typically law enforcement and towing companies, and occasionally highway agency service patrol vehicles.
