Projects on existing roadways call for a flexible, practical, and performance-based approach to design. The EPG encourages flexible and practical design, which emphasizes the role of the planning and design teams in determining appropriate design dimensions based on project-specific conditions and existing and future roadway performance, more than on meeting specific nominal design criteria.

9/9/15: Guidance for Temporary Concrete Traffic Barrier Standard Drawings now reflects recent crash studies. Of particular note, the Midwest State's Regional Pooled Fund Research Program Report  TRP-03-113-03 (revised) recommends the design deflection limit for free standing (unpinned) temporary traffic barrier be set at 2 feet. This would reduce instances in which temporary traffic barrier would require pinning. 
 
'''[[606.1 Guardrail#606.1.3.2 Approved Crashworthy End Terminals|EPG 606.1.3.2 Approved Crashworthy End Terminals]]'''
 
9/9/15: Previously, a contractor would typically choose the cheapest end treatment from the approved list and provide that unit whether it was the best solution or not.  For that reason, end treatments are now further subdivided to more closely match the hardware to its intended use, performance, reusability and cost of repair.   
 
'''[http://epg.modot.org/index.php?title=106.3.2.59_TM-59%2C_Determination_of_the_International_Roughness_Index#106.3.2.59.3_Construction_Acceptance_Procedures Determination of the International Roughness Index]'''
 
9/9/15: Guidance now codifies the intent that no filters may be used to distort the true road profile measurement with an inertial profiler.
 
'''Airport Requirements'''
 
9/9/15: Guidance in [[:Category:235 Preliminary Plans#235.8 Airports|EPG 235.8 Airports]] now details the requirements for Obstruction Evaluation/Airport Airspace Analysis that ensure that FAA filing requirements are met when MoDOT operations impact FAA airspace.  
 
'''[[133.4 Snow and Ice Control Operations#Non-Continuous Operations Routes:|EPG 133.4 Snow and Ice Control Operations]]'''
 
9/8/15: Guidance for non-continuous operations routes and plowing was clarified. It has never been intended to meet objectives on the non-continuous treatment routes "as soon as possible". Rather, operations on these routes may be suspended overnight and at times when progress is not being made.
 
'''[[751.50 Standard Detailing Notes|EPG 751.50 Standard Detailing Notes]]'''
 
9/8/15: Clarified numerous notes and revised the Bridge Approach Slab Notes to match the recent release of new Bridge Approach Slab std. drawings.
 
'''Series I Protective Coating '''
 
8/28/15: Guidance in [[751.14 Steel Superstructure#751.14.5.8 Protective Coating Requirements|EPG 751.14.5.8 Protective Coating Requirements]] and [[751.50 Standard Detailing Notes#A4. Protective Coatings|EPG 751.50 Standard Detailing Notes A4. Protective Coatings]] was revised to conform to Sec 1081, clarifying when to use System I.
 
'''[[Other Aspects of Pavement Design#Purpose of Alternate and Optional Pavement Bidding|Alternate Paving Minimal Thickness]]'''
 
8/27/15:  Guidance was clarified to indicate the minimal thickness of pavement must be 7" for a Life Cycle Cost Adjustment to be applied.
 
'''[[:Category:129 Public Involvement#129.4 Coordination with other Agencies|EPG 129.4 Coordination with other Agencies]]'''
 
8/25/15: Guidance was clarified about the list of agencies with whom to coordinate the environmental process.

8/19/15: This new subarticle updates EPG guidance to current practice for concrete design.
 
'''[[:Category:806 Pollution, Erosion and Sediment Control#For projects performed by MoDOT’s internal staff|EPG 806.7.6 Pollution, Erosion and Sediment Control Basis of Payment]]'''
 
8/17/15: To maintain compliance with the Consent Decree's requirements, erosion control change order guidance has been provided.
 
'''[[:Category:109 Measurement and Payment#Erosion Control Change Orders|Erosion Control Change Orders]]'''
 
8/11/15: Guidance was updated in EPG 109.12 Change Orders because the EPA is now mandating the Stormwater Compliance and Environmental Specialist be able to execute change orders up to $100,000 for erosion control items.
 
'''ET-Plus Policy'''
 
8/7/15: In [[606.1 Guardrail#All guardrail end terminals that are not currently|EPG 606.1.3.1 3R/4R Projects]], guidance now requires ET-Plus end treatment devices to be replaced during construction or repair, including anytime existing adjacent guardrail is raised or the end treatment modified.
 
'''Concrete Coring'''
 
8/6/15: In several locations in EPG 751 LRFD Bridge Design Guidelines, references to concrete coring of drilled shafts were removed because it is no longer specified on a set of bridge plans for integrity testing of drilled shafts. During construction, concrete coring may still be called for by the engineer when there is a dispute with the sonic logging testing.
 
'''[[Media:234.2.1.1 Diamond Interchange.pdf|Geometric Layout of a Diamond Interchange]]'''
 
7/31/15: In [[234.2 Diamond Interchanges#234.2.1.1 Ramp and Preliminary Plan Criteria|EPG 234.2.1.1 Ramp and Preliminary Plan Criteria]], the 700 ft. dimension between ramp termini previously shown in this diagram was revised to 800 ft. to reflect recent USDOT/FHWA guidance.

Our mission is to provide a world-class transportation system that is
safe, innovative, reliable and dedicated to a prosperous Missouri.

MoDOT’s three pillars of “Safety, Service and Stability” steer our leadership and employees. Our commitment to safety includes keeping both customers and ourselves safe. Our service includes providing outstanding customer service, delivering transportation solutions of great value and using resources wisely. Keeping roads and bridges in good condition, operating a reliable and convenient transportation system, and advancing Missouri’s economic development reflect our commitment to stability.
Innovative concepts, such as Practical Design and design-build, are used to deliver our commitments. These and other forward-thinking concepts shape the content of the ENGINEERING POLICY GUIDE (EPG). This document provides a single reference for all engineering and engineering-related Bridge, Construction, Design, Highway Safety & Traffic, Maintenance, Planning and Right of Way guidance.

The design concepts and criteria within the Engineering Policy Guide (EPG) are intended for use when designing new construction projects on new locations or designing reconstruction projects on existing locations. Projects on existing roadways call for a flexible, practical, and performance-based approach to design. The EPG encourages flexible and practical design, which emphasizes the role of the planning and design teams in determining appropriate design dimensions based on project-specific conditions and existing and future roadway performance, more than on meeting specific nominal design criteria. Although new design values and concepts may be presented throughout the EPG, this does not imply that existing roadways are unsafe, nor does it mandate the initiation of projects to improve existing roadways. While the EPG does include nearly all engineering related aspects of roadway design and maintenance it is not all encompassing. The use of properly equipped and maintained vehicles, operated by a capable user, is also pertinent to the safe and efficient operation of a transportation facility.
