MI Engineering personnel have over 65 years of experience designing bridges in North Carolina, South Carolina, Virginia, and West Virginia. From the simplest cored slab span to the most complex curved steel girders, every project is held to the same high standards for quality design and on time delivery. Example projects highlighting recent staff experience are shown below.

While at Ko & Associates, PC in 2004 MI Engineering staff designed two bridges for the US 70 Clayton Bypass project on an accelerated schedule for the North Carolina Department of Transportation. The bridge design was completed in less than 6 months and construction began 6 months later.
Bridge number 1087 is a four-span continuous curved steel girder bridge with a total length of 233.0 m (764.4 ft) and a clear roadway width of 9.0 m (29.5 ft). Bridge number 1088 is a five-span continuous curved steel girder bridge with a total length of 282.0 m (925.2 ft) and a clear roadway width of 12.0 m (39.3 ft). Both bridges have radial end bents on piles. Interior bents are radial hammerhead bents, except bent 1 at both bridges are double hammerheads skewed at 50 degrees from radial.

While at Ko & Associates, PC in 2001 MI Engineering staff designed 4 bridges for the NCDOT as part of the US 117 Bypass around Wilson, NC. Construction on the bypass began in September 2003 and was completed in September 2006.
A pair of dual bridges carries US 117 over the CSX Railroad. The superstructures consist of concrete deck on Type IV AASHTO girders made continuous for live load. The substructure consists of concrete end bents and post and beam interior bents supported by steel H-piles. A third structure carries an interchange ramp over the same section of railroad. Superstructure and substructure are similar to the dual bridges, but an increased skew angle makes the spans slightly longer.
The fourth bridge carries an interchange ramp over both lanes of US-264. This two-span continuous curved steel plate girder has severe skews up to to 145 degrees.

While at Ko & Associates, PC in 2000 MI Engineering staff designed three (3) structures for NCDOT as part of the Greensboro Outer Loop (I-840) interchange with I-40. The first two steel plate girder structures will carry
I-840 over both lanes of I-40 and a ramp.
The third bridge provided many unique design challenges. The roadway followed a curve-spiral-tangent alignment with a transitioning cross-slope. The three-span continuous steel girders were curved along segments with different radii in order to approximate the spiral. One end bent is located behind an MSE wall adjacent to the shoulder in order to limit the span length. The overall length of the bridge is 188.4 m (618 ft).
