Improvements (West Clay to Kingshighway).

Dear Consultant:

The City of Saint Charles has an interest in securing professional services for work associated with

the following projects:

First Capitol & Kingshighway Roundabout (CMAQ-7302(721))

The project improvements include a new roundabout at First Capitol Drive and Kingshighway Street

to replace the existing signalized intersection. Median refuge islands will be installed on each leg of

the roundabout. The existing pavement at this intersection is in fair condition and will be replaced

with full depth concrete pavement as needed to construct the new roundabout.

The project also includes a new 10' wide shared use path (SUP) along the west side of First Capitol

Drive connecting to new SUP to be constructed between Kingshighway and Fifth Street (previously

awarded STP funds).

First Capitol Shared Use Path Bridge (TAP-7302(722))

The project will construct a 90 foot span SUP bridge over First Capitol Drive connecting the

Lindenwood University library to public sidewalks along the south side of First Capitol. All

improvements shall meet ADA.

First Capitol Improvements (West Clay to Kingshighway) (Design Non-Participating)

The project improvements include a new roundabout at First Capitol Drive and Tompkins Street to

replace the existing signalized intersection. Median refuge islands will be installed on each leg of

the roundabout. The existing pavement at this intersection is in fair condition and will be replaced

with full depth concrete pavement as needed to construct the new roundabout. Remaining

pavement will be replaced or mill/filled as needed.

The project also includes a new 10' wide shared use path (SUP) along the north/west side of First

Capitol Drive continuing up West Clay Street to connect to existing SUP. Existing center median will

be replaced with concrete barrier. Advanced detection will be installed at the West Clay signal.
