Project Description The City of St. Peters is seeking funds to construct the expansion of the Salt River Road/MO 370 Interchange to provide access to
westbound/southbound MO 370 and I-70 from eastbound Salt River Rd and access to westbound Salt River Rd from
eastbound/northbound MO 370 and I-70.
The proposed interchange improvements will:
Reduce reliance on the existing I-70 interchanges at Mid Rivers Mall Dr and Cave Springs Rd for commuter and freight
traffic.
Provide direct commuter and freight access to MO 370 and I-70 for the Premier 370 Business Park, a designated Mega
Freight Center.
Allow Salt River Rd to be used as a diversion route during incidents on I-70 that occur between MO 370 and MO 79.
Currently it is difficult to access Salt River Rd from westbound I-70 and it is difficult to access eastbound I-70 from Salt
River Rd. While direct ramps are provided at the MO370/I-70 interchange for these traffic movements these ramps are not
currently provided at the MO370/Salt River Road interchange. This project will provide this missing connection.
The City of St. Peters is working closely with MoDOT and FHWA to prepare an Access Justification Report (AJR) for the
project.
Phase 2/Ramps 2 and 3 of this project (submitted under this application) will construct ramps to connect eastbound/northbound
MO 370 and I-70 with westbound Salt River Rd. Ramp 2 will consist of a 14 ft wide concrete ramp, with an 8 ft outside and 4 ft
inside shoulder, extending from eastbound MO 370 to the westbound exit ramp from MO 370/Salt River Rd ramp to Spencer Rd.
The ramp will have a 40 mph design speed and connect to MO 370 utilizing the existing shoulder. An auxiliary lane will be built
to connect Ramp 2 to the MO 370 entrance ramp from westbound I-70. Three new bridges will be constructed with Ramp 2 over
Premier Pkwy, over MO 370, and over the MO 370/Salt River Rd interchange ramps. A new westbound exit ramp (Ramp 3) to
Spencer Rd will be constructed with Ramp 2. Ramp 3 will consist of a 12 ft wide concrete ramp, with an 8 ft outside and 4 ft
inside shoulder. Ramp 3 will have a 40 mph design speed. Part of the westbound entrance ramp at the Salt River Rd/Spencer Rd
interchange will be widened to accommodate the westbound through traffic movement from Ramp 2.
Phase 1/Ramp 1 of this project (submitted under a separate application) will construct ramps to connect eastbound Salt River Rd
with westbound/southbound MO 370 and I-70. Ramp 1 will consist of a 14 ft wide concrete ramp, with an 8 ft outside and 4 foot
inside shoulder, extending from the Spencer Rd to Salt River Rd entrance ramp to westbound MO 370. The ramp will have a 40
mph design speed and connect to the existing three lane section of MO 370 utilizing the existing shoulder. An auxiliary lane will
be built to connect the ramp to the MO 370 ramp to Eastbound I-70. The bridge over Premier Pkwy will be widened.

CBB Job Number: Traffic Forecast Memorandum Salt River Road & Missouri Route 370 Interchange Modifications Access Justification Report
Project 108-2018 CBB has prepared traffic forecasts for the Salt River Road & Missouri Route 370 (MO 370) Interchange Access Justification Report (AJR). The purpose of this memorandum is to provide a brief description of the procedures used to forecast traffic volumes to be used in the evaluation of the proposed modifications to the Salt River Road & MO 370 interchange in Saint Peters, MO. The study corridor includes Interstate 70 (I-70) between Mid Rivers Mall Drive interchange (to the west) and Cave Springs Road interchange (to the east) and MO 370 between Truman Boulevard interchange and I-70 interchange. The objective of this work was to develop traffic volume forecasts for future scenarios for use in evaluating the proposed improvements at the Salt River Road & MO 370 interchange. As an initial step in the process, manual turning movement counts were collected on a typical weekday from 7:00 AM to 9:00 AM and 4:00 PM to 6:00 PM at the following intersections and ramps in 2018:
• Mid Rivers Mall Drive at Eastbound I-70 Ramps (November 2018) • Mid Rivers Mall Drive at Westbound I-70 Ramps (November 2018) • Mid Rivers Mall Drive at Main Street/I-70 North Outer Road (November 2018) • Cave Springs at Road Mexico Road (November 2018) • Cave Springs at Veterans Memorial Parkway (November 2018) • Cave Springs at Eastbound I-70 Ramps (November 2018) • Cave Springs at Westbound I-70 Ramps (November 2018) • Cave Springs at West Clay Street (November 2018) • Westbound MO 370 to Eastbound I-70 Ramp (November 2018) • Westbound MO 370 to Westbound I-70 Ramp (November 2018)
Traffic Forecast Memorandum – Salt River Road AJR
December 26, 2018 Page 2
CBB utilized turning movement counts completed in 2017 for the Salt River Road and MO 370 Interchange Study for the following intersections and ramps:
• Spencer Road at Westbound Salt River Road Ramps (November 2017) • Spencer Road at Eastbound Salt River Road Ramps (November 2017) • Westbound MO 370 to Westbound Salt River Road Ramp (November 2017) • Eastbound Salt River Road to Eastbound MO 370 (November 2017) • Harry S. Truman Boulevard at Westbound MO 370 Ramps (September 2017) • Harry S. Truman Boulevard at Eastbound MO 370 Ramps (September 2017) • Harry S. Truman Boulevard at Premier Parkway (September 2017) • Eastbound I-70 to Eastbound MO 370 Ramp (November 2017) • Westbound I-70 to Eastbound MO 370 Ramp (November 2017)
CBB also utilized peak period and daily 2018 traffic volume data for I-70 obtained from MoDOT's ATMS Data Portal. After obtaining existing traffic volume counts, the traffic growth for the roadways was determined by evaluating historical growth trends, utilizing the St. Charles Count Travel Demand Model, and accounting for future land use plans within the study area. In particular, the Premier 370 Business Park in particular is an 850-acre business community positioned near the MO 370 and I-70 interchange. The primary source of traffic growth on the local roadway network in the immediate study area will be attributed to the trips generated by the developments within the Premier 370 Business Park. CBB utilized the projected traffic volumes from the Traffic Impact Study for the Proposed Project LOU Development, dated February 2018, for the area between Spencer Road to the west and Truman Boulevard to the east as well as MO 370. The estimated traffic volumes were based on currently approved developments within Premier 370 Business Park as well as a full development of the entire Premier 370 Business Park. The study area for this AJR expands from the Project Lou study area to include I-70 and interchanges with Mid Rivers Mall Drive, and Cave Springs Road as well as operations along MO 370. Figure 1 illustrates the locations where traffic volumes were distributed from the Project Lou study area. The anticipated directional distribution during the AM and PM peak hours for the projected traffic volumes for each individual location would be as follows:
• Location 1 o 40% to/from the west on I-70 via Mid Rivers Mall Drive Interchange; o 40% to/from the east on I-70 via Mid Rivers Mall Drive Interchange; o 10% to/from the west on Salt River Road; o 10% to/from the south on Mid Rivers Mall Drive;
• Location 2 o 40% to/from the west on I-70 via Mid Rivers Mall Drive Interchange; o 40% to/from the east on I-70 via Mid Rivers Mall Drive Interchange; o 10% to/from the south on Spencer Road;
Traffic Forecast Memorandum – Salt River Road AJR
December 26, 2018 Page 3
Figure 1: Locations where Traffic Volumes were Distributed from the Project Lou Study Area
• Location 3 o 90% to/from the west on I-70 via MO 370 Interchange; o 10% to/from the east on I-70 via MO 370 Interchange;
• Location 4 o 40% to/from the west on I-70 via Cave Springs Road Interchange; o 40% to/from the east on I-70 via Cave Springs Road Interchange; o 10% to/from the south on Muegge Road;
• Location 5 o 50% to/from the west on I-70 via Cave Springs Road Interchange; and o 50% to/from the east on I-70 via Cave Springs Road Interchange.
Future traffic volumes along I-70 were estimated based on historic growth trends as well as output from the St. Charles County travel demand model. Figure 2 illustrates the historic counts supplied by MoDOT AADT maps. As can be seen, the I-70 corridor has experienced steady annual traffic growth since the mid-1970s. Going forward, the growth rate is expected to continue. The project growth rate for I-70 between 2018 and 2040 is approximately 35%. Additionally, traffic volume on Mid Rivers Mall Drive and Cave Springs Road is expected to grow between 10-15%. The proposed traffic volumes are provided in the Appendix.

Figure 2: Historical and Projected I-70 Traffic Volumes Finally, the MoDOT yearly count map was utilized to determine the existing daily truck volumes along I-70 near the MO 370 interchange, which is 12%. Additionally, the ramp counts completed by CBB obtained the truck percentages along MO 370 during the peak hours was on average 12%. CBB will utilize a truck percentage of 12% along I-70 and MO 370 for the 2020 traffic volume scenario. It should be noted that CBB reviewed the I-70 Planning and Environmental Linkages (PEL) Study Conditions Assessment Report, dated May 2017, for the I-70 corridor between Interstate 64 (I-64) IN St. Charles County, Missouri to the end of the express lanes in the City of St. Louis. CBB compared the I-70 peak hour traffic volumes in the PEL study to the peak hour traffic volumes obtained by the MoDOT's ATMS Data Portal. The comparison showed that the MoDOT's ATMS Data Portal peak hour traffic volumes are comparable to the I-70 PEL Study peak hour traffic volumes for I-70. St. Charles County has included a freight component in their travel demand model. This model shows increasing truck volumes in the future. The anticipated truck percentage along I-70 and MO 370 is 13% and 15%, respectively, for the 2040 traffic volume scenario. We appreciate your review of the above technical assumptions for the Salt River Road and MO 370 AJR. Very truly yours, Shawn Leight, PE, PTOE, PTP Vice President
