By Regional Average

⭐ NORTHEAST REGION — STATE AVERAGE GRADES

All values use the 100-point numeric scale after each state's infrastructure letter grade is determined from the 18-category Grade Matrix.

#	State	Letter Grade	Numeric Average
1	Massachusetts	C	75.39
2	New York	C	73.67
3	New Jersey	C	74.50
4	Connecticut	C	73.61
5	Rhode Island	C	73.72
6	Pennsylvania	C−	72.56
7	New Hampshire	C	73.33
8	Maine	C−	71.33
9	Vermont	C−	72.83

🌟 NORTHEAST REGIONAL INFRASTRUCTURE AVERAGE

73.44 — C

Method: Each state's 18 category grades are converted to the locked numeric grade scale first. The resulting state numeric averages are then averaged to produce the Northeast regional infrastructure average.

⭐ SOUTHERN REGION — STATE LETTER GRADES

Method: Each state's 18 category letter grades are converted to the locked numeric scale. Those 18 numeric values are averaged to produce the state's infrastructure average, which is then expressed as a letter grade.

1	Virginia	C	74.56
2	Tennessee	C-	71.89
3	Florida	C-	72.61
4	Georgia	C-	72.39

Southern Regional Infrastructure Average

70.43 → C-

LOCKED GRADE → NUMERIC SCALE: A+ 100 • A 96 • A− 91 • B+ 87 • B 84 • B− 80 • C+ 77 • C 73 • C− 70 • D+ 67 • D 64 • D− 61 • F 55.

16 SOUTHERN STATES: All 16 state letter grades have now been added using the existing 50-state × 18-category Grade Matrix. No Southern state grade was invented or copied from another state.

DATA STATUS: These are model/matrix grades based on the current project Grade Matrix, not claims that ASCE publishes an official infrastructure average for each state.

⭐ MIDWEST REGION — STATE LETTER GRADES

Method: Each state's 18 category letter grades are converted to the locked numeric scale. Those 18 numeric values are averaged to produce the state's infrastructure average, which is then expressed as a letter grade.

1	Minnesota	C	74.06
2	Ohio	C-	72.11
3	Missouri	C-	70.61
