Building Roads

The rules for building roads are either 1) Too Complicated, 2) Too Expensive or 3) Non-Existent. This is a very simplified way of treating road building, which includes materials and carriage in.

Road Building is a simple matter of picking a Style, a Width, and applying that to the distance (in miles).

Road Style

Style	Cost per Mile	Labourers required to construct 1 mile in 1 month	Special
Dirt	50gp	12
Hard Packed Dirt	75gp	24
Gravel	350gp	16	Providing gravel reduces the cost to 50gp
Cobbled	500gp	48	Providing rough stone reduces the cost to 100gp
Paved	750gp	48	Providing smooth stone reduces the cost to 200gp
Shoon	2,000gp	160	Providing Light & Coarse gravel, Rough Stone, and Smooth stone reduces the cost to 450gp

Road Width

Width	Multiplier
Single Carriage (5’)	1x
Dual Carriage (10’)	2x
Highway (15’)	2.5x

Building Bridges

Much like roads, building bridges is also overly complicated. These rules simplify the creation of bridges, like the roads above.

Bridge Style

Style	Cost per Foot	Labourers required to construct 20’ in 1 month	Special
Wood	75gp	4	Providing wood reduces the cost to 30gp
Rough Stone	200gp	20	Providing rough stone reduces the cost to 55gp
Smooth Stone	250gp	20	Providing smooth stone reduces the cost to 55gp
Arched	+25gp	-	Making a bridge arched allows you to ignore depth & pylon stability – the length of a bridge is limited to the designer’s Knowledge (Engineering) x 2

Depth Below Bridge

Depth	Multiplier
0-5’	x1
6-15’	x1.5
16-30’	x2
31-50’	x3
51-100’	x5
101-200’	x10
201+	Impossible

Pylon Stability

Ground is…	Multiplier
Bed Rock	1x
Hard Packed Dirt or gravel	1.5x
Mud	3x

Bridge Width

Width	Multiplier
Single Carriage (5’)	1x
Dual Carriage (10’)	2.5x
Highway (15’)	3.5x

Examples

Ex 1: 60’ rough stone single carriage bridge over a gravel river ford (average of 2’ deep)

60 × 200gp x 1 × 1.5 × 1 = 18,000gp

Ex 2: 60’ smooth stone double carriage bridge over a deep muddy river (average of 8’ deep)

60 × 250gp x 1.5 × 3 × 2.5 = 168,750gp

Ex 3: 60’ smooth stone arched double carriage bridge over a deep muddy river (average of 8’ deep)

60 × 275gp x 1 × 1 × 2.5 = 41,250gp

Ex 4: 30’ rough stone arched single carriage bridge over a deep chasm (over 300’ deep)

30 × 225gp x 1 × 1 × 2.5 = 16,875gp
